This annotated chronology is based on the data sources that follow each entry. Public sources often provide conflicting information on classified military programs. In some cases we are unable to resolve these discrepancies, in others we have deliberately refrained from doing so to highlight the potential influence of false or misleading information as it appeared over time. In many cases, we are unable to independently verify claims. Hence in reviewing this chronology, readers should take into account the credibility of the sources employed here.

Inclusion in this chronology does not necessarily indicate that a particular development is of direct or indirect proliferation significance. Some entries provide international or domestic context for technological development and national policymaking. Moreover, some entries may refer to developments with positive consequences for nonproliferation.

In a review of foreign radio broadcasts, Tehran Radio states, "Last week, the foreign radios spread a lie that our country's Prime Minister, Mr. Musavi, in his budget speech to the Islamic Majlis, had announced that Iran has started manufacturing chemical weapons. The foreign radios rapidly magnified this fabricated news and reflected it across the world." After playing an audio tape of a BBC news report in Persian, Tehran Radio states, "As you heard, the state-controlled BBC radio claims that the Islamic Republic of Iran has begun manufacturing chemical weapons. The state-controlled radio of America [VOA], broadcasting a similar report, also claimed that Iran's prime minister had confessed to manufacturing chemical weapons....[The foreign radios] even went so far that the state-controlled BBC radio claimed that Iran had placed chemical weapons at the disposal of Libya in exchange for a certain type of missile....Such fabrications of foreign radios demonstrate the sinister nature of these radios, which use a fabricated report as a base for fabricating more news."

An Afghan rebel being trained in combat tactics at a training camp in Iran comments on CW training he received: "In conducting combat training operations, we were often forced to use chemical weapons [such as] tear gas cartridges and grenades. Once I was severely poisoned. Since that time, my eyes water constantly. Occasionally, when we did not go out at night to the range but stayed in school, chemical weapons alarms were conducted. In various parts of the barracks tear gas grenades exploded and blank cartridges were fired. We had to jump out of bed instantly, put on our masks, grab our weapons, and apply ourselves to perimeter defense. Those who did not manage to put on their gas masks were seriously poisoned." [Note: This report was taken by a Soviet newspaper by an Afghan rebel that defected to the communist Afghan government in Kabul.]

US intelligence sources report that US allies were among the states that exported a total of $1.5 billion in military equipment to Iran in 1987. The largest supplier of arms to Iran in 1987 was China, which shipped $600 million worth of artillery, ammunition, and Silkworm missiles. China also reportedly sold industrial machinery needed to indigenously produce weapons to Iran. North Korea sold $400 million in military hardware to Iran in 1987, including artillery, fast patrol boats, and Soviet-design Scud surface-to-surface missiles. Spain and Portugal sent $150 million worth of military equipment to Iran; Japanese firms $100 million in spare parts and trucks; West German and Swiss firms chemical warfare defensive gear; and Warsaw Pact countries $340 million worth of military hardware. Available sources show no evidence of Soviet arms transfers to Iran. The totals were compiled as part of an updated Pentagon analysis of foreign military transactions with Iran.

However, in view of the length of the fronts and the existence of lofty heights, especially on the western fronts, we decided to manufacture more modern equipment with greater and better application. Recently this equipment has been manufactured and made ready for use, and its mass production as already started.' He said, 'this equipment comprises a container with a capacity of 1,000 liters, and a limiter system, which can be filled with surface water, and two exit pipes which installed by means of a pylon and a flexible hose in the back of the vehicle, which can completely empty all the contents of the tank in four minutes. Another characteristic of this equipment is that it can directly use the power of vehicle engines, and the gearbox installed on the equipment, which can transfer the contents to the pumps, through which one can direct the contents with a greater range at the bombed areas.'"

Facts on File reports the sequence of events as follows: Iran claims to have taken the town of Halabja as part of a three-pronged offensive by its forces and Kurdish fighters. Iraqi government forces collapsed and were taken prisoner after a battle around the town of Dojaila. At that point, the Iraqi garrison was apparently "arrested" by Dojaila's Kurdish population. Some survivors of the fighting claim that the Patriotic Union of Kurdistan had encircled Halabja. Western experts claim that the Kurdish role in the capture of the town might explain why the chemical attack occurred, especially since it was punitive rather than tactical in nature. Accounts of both survivors and Iranian officials agreed that Iraqi warplanes bombed the town with a combination of conventional and chemical weapons between 16-17 March. Some of the victims included Iranian Revolution Guard Corps (IRGC) troops who had just entered the town when the Iraqi aircraft began bombing the town with CW. Most of the Iranians survived uninjured because of CW protective gear. The US states that Iran also may have used CW in attacking Halabja, however, according to Facts on File, this is the only claim that Iran used CW in Halabja.

It is an act defined as a crime against humanity." Mahallati demands the Security Council "immediately condemn Iraq's use of chemical warfare, call for an immediate end to such practice, and immediately dispatch a mission to investigate." He also asked that the Security Council convene a session solely on the topic of Iraq's CW usage "independently from other war issues." He claims that as many as 5,000 civilians killed and an equal number of people wounded.

David Hirst reports that according to Iranian officials, Iraqi Mirage fighter planes dropped cyanide on the Kurdish people of Halabja. Dr. Sayyid Furutan says that "one bomb holds a hundred liters and on a cold day the vapor can quickly spread 500 meters. These people had no chance," he says as he pointed to what remained of a cyanide-carrying bomb. He goes on to state that in other areas of the town, planes dropped nerve gas along with mustard. "You can save the victims of nerve gas if you treat them quickly, and we saved many." However, the mustard gas injured many people. Hirst and other reporters visited a hospital in Bakhtaran where some of the victims less seriously injured are receiving treatment. More seriously injured victims have been transferred to Tehran where the Azadi stadium has been converted to allow treatment of the victims. All of the victims, numbering in the thousands, are reportedly Iraqi Kurdish civilians except for a handful of Iranian soldiers who did not don their gas masks in time. An Iranian journalist reported that he had observed the Kurdish townspeople of Halabja "hiding in the tobacco factory after we had entered the town without a shot being fired." He states that he had "wondered what they were all doing" until 6:30 pm when Iraqi Mirage fighter planes attacked the town with CW. [Note: There has been no confirmation that hydrogen cyanide or cyanogen chloride were used by either Iraq or Iran against targets in Kurdistan or elsewhere.]

US State Department spokesman Charles Redman says with regard to the Iraqi use of CW on the Kurdish village of Halabja, "There are indications that Iran may also have used chemical artillery shells in this fighting." He did not provide any specific details about what the "indications" were. Redman did, however, mention that both Iran and Iraq were able to produce CW indigenously, and that both countries were trying to stockpile CW. Redman states that the United States "calls upon Iraq and Iran to desist immediately from any further use of chemical weapons, which are an offense to civilization and humanity." When asked to provide evidence of Iranian CW use, Redman responds that he was "not prepared to go into the kind of evidence we have." US officials state that both combatants can produce CW indigenously. An unnamed US official, however, claimed that the evidence of Iraqi CW use at Halabja was far more convincing than that of Iranian use there.

The Special Security Office of the US Defense Intelligence Agency states, "Most of the casualties in Halabja were reportedly caused by cyanogen chlorine [chloride]. This agent has never been used by Iraq, but Iran has shown interest in it. Mustard gas casualties in the town were probably caused by Iraqi weapons because Iran has never been noted using that agent."

The United States, Iran, and the Red Cross condemn Iraq for launching a CW attack against its Kurdish population last week. Iraq immediately denies attacking Kurdish villages with CW and instead blames Iran for the massacre. Meanwhile, Iran has escorted foreign media to the scene of the attacks. IRNA reports that Iraqi planes dropped CW munitions on "innocent and defenseless Kurdish inhabitants in Iranian liberated towns and villages in northeastern Iraq last week." IRNA reports the attacks killed 5,000 and wounded 5,000 more with the dead suffering "from burns on their eyes, faces, hands, feet and lungs, as well as disturbances in their nervous systems."

At Iranian War Information Headquarters Minister, Kamal Kharrazi blames the UN Security Council for not stepping in earlier to prevent Iraqi use of CW. While addressing a press conference, Kharrazi states that the "indifferent attitude" of the Security Council would limit its chances of leading Gulf War peace efforts. He further warns that even though Iran has decided against using CW thus far, it would be forced to reconsider this self-imposed ban should the Security Council remain silent on the issue.

23 March 1988
Kharrazi, in response to a question posed by a BBC correspondent about a possible Iranian retaliation using CW, states that "we have the capability to do this. However, the Islamic Republic of Iran's use of chemical weapons depends on the reaction of the Security Council to this Iraqi action. We have not yet taken a definite decision in this respect but if no important step is taken to stop Iraq using chemical weapons, then we will be forced to defend ourselves."
—"Iran Prepared to use Chemical Weapons," British Broadcasting Corporation, BBC Summary of World Broadcasts, 25 March 1988, Part 4, p. A1.

23 March 1988
Kharrazi states, "We haven't taken any decision yet" on using chemical weapons. "But as long as the international community refuses to condemn Iraq using chemical weapons against towns and villages we may be forced to do so....We think that some members of the Security Council may have been involved in the attacking of Iranian cities and may also have been involved in the planning of chemical warfare attacks against the captured Kurdish town in Iraq of Halabja. The Security Council is more worried that Iraq will be defeated than that its crimes will be punished."

23 March 1988
Iran states the cyanide that hit Halabja was delivered by 100-liter containers that vaporized the gas on impact. Doctors on the scene say that evidence clearly shows that cyanide was used along with mustard and nerve gas (although what this evidence was precisely is still unknown). Reporters taken to the scene of the attack were issued gas masks and medical kits as a precautionary measure by Iranian officials for fear of another Iraqi attack. Iran claims that the town was hit in three waves of gas attacks, beginning on 16 March in the afternoon and continuing into the next day. Iran states that cyanide was used over large portions of the city, while mustard and nerve gas were deployed in other districts. Iran states that most of its Revolutionary Guards and thousands of Halabja citizens had already left the town before the first bombing raid. However, up to half of the town's population appear to have still been in the town when the first bombs fell.

Hashemi Rafsanjani warns that Iran will have no other choice but to retaliate with chemical weapons if Iraqi CW attacks continue. The Associated Press (AP) states that "the intensity of Tehran's accusations against Iraq in recent days has heightened fears that the Iranians may be seeking to justify using chemical weapons of their own." The AP quotes Don Kerr of the International Institute of Strategic Studies in London as stating that "it's entirely likely that the Iranians could do so. They've had these weapons used against them for a long time." The AP notes that since 1984, Iran has accused Iraq of using CW against them on more than 100 occasions–primarily against Iranian troops. According to the AP, "Iran's chief military spokesman, Kamal Kharrazi, has said this country is producing chemical weapons." The analysts and diplomatic sources, who spoke on condition of anonymity, said that Iranian chemical weapons are believed to be mainly mustard and phosgene gases. Kerr noted, "These are relatively simple to manufacture from readily available industrial components, as is hydrogen cyanide. Only the more complex nerve gases are likely to pose a chemical challenge to the Iranians."
—Ed Blanche, "Chemical Warfare Threat Mounts in Gulf War," Associated Press, 24 March 1988.

Hashemi Rafsanjani states on Tehran Radio that "we asked the UN to send experts to the Halabja region to inspect the effects of the chemical weapons. If the international organizations refuse to take any step to punish Iraq, we shall not remain idle. We have the technology to produce chemical weapons, and although we have not exploited this yet, we will not remain idle forever."

At a press conference, Rafsanjani states that "We are discontented with the UN Secretary General because he has not done his duty in preventing the Iraqis from using chemical weapons and attacking Iranian cities."
—"Iran to Send Envoy to Meet UN Chief," Xinhua General Overseas News Service (PRC), 24 March 1988, item number: 0324207.

24 March 1988
At a press conference, Rafsanjani states, "I want to thank the correspondents for having taken the trouble to go to Halabjah, and thus having started to reflect this calamity to the world. The events of the past two or three weeks are clearly unprecedented and worthy of serious consideration. Possibly the fact that the allegiance of the occupied cities' residents was entirely to the conquering forces and that they were very happy to see these forces enter cities is a rare or even unprecedented phenomenon. It is interesting to note that these cities were within the range of the Islamic Republic's artillery and that very recently Saddam [Husayn] had alleged that we were shelling them with our artillery. Had the residents of these cities been harmed by our artillery, they would not have displayed such sincere feelings towards us. Perhaps it is also unprecedented that the ruler of these cities so cruelly bombed his own people because they did not co-operate with his forces. The surprising thing is that the news media and world observers, and especially governments, do not consider these to be important points. History will judge the calamity of the chemical bombing of Halabjah and surrounding cities, and will put the military, political, and propaganda powers of today's world on trial. If Iraq had been punished last year when it used chemical weapons, as the UN also confirmed, this calamity would not have taken place....We asked the UN to send experts to inspect the calamity. But we see that in the UN and Security Council, the USA and France are preventing the dispatch of UN experts. By claiming that Iran may have also used chemical weapons, the Americans have cast the first shadow of doubt. However, the facts are so strong that whoever tries to raise doubts will have only disgraced himself."

Rafsanjani, in response to a question posed by a reporter on whether Iran would retaliate with CW if the international community remains silent on the issue, replies, "With the presence of correspondents in the operational theatre, we see, more or less, that the silence has been broken and that, fortunately, reports and reactions are [accumulating]. If this trend continues, it will be effective. But if appropriate organizations do not take steps, naturally we cannot sit idly by and witness the continuation of these crimes. We have stated previously that we do have the technology to manufacture chemicals and all the types of gases being used now. Fortunately, so far we have been able to restrain ourselves and not use them. But there is no guarantee that this restraint will continue forever."

A reporter further asks Rafsanjani to comment on the US condemnation of the Iraqi attack. Rafsanjani states, "I, too, read these reports today. We thank the USA for having condemned this. However, it has also committed an unpious act. While condemning this, they have said that it is alleged that Iran has also used chemical shells in the region. This is a lie. They should present facts. Also, they did not clearly refer to Iraq. They should explicitly condemn this crime by Iraq. Any weakness in condemnation will make Iraq bolder. I do not think there is the least doubt that this crime was carried out by Iraq intentionally and mischievously, and against its own people. We have a document proving that one of the Iraqi regional officers informed Baghdad that the region's people had been asked to take up arms and to fight the Iranians but that they refused to do so; thus, they should be punished. The answer from Baghdad was that they would soon be punished; and their punishment was what you, the correspondents, saw in the streets of Halabjah, in the hospitals and in the convalescent centers. This should be clearly, explicitly and decisively condemned. Meanwhile, it should be pointed out that condemnation so weak is not enough. Action should be taken against the aggressor; and this is what various countries are expected to do."

When asked about whether there is only a military solution to end the war, Rafsanjani states, "We intend to send someone to the UN for talks with the Secretary-General. But we have a recent bone to pick with the Secretary-General too, because he has not carried out the duty assigned to him by the UN to send an expert on chemical affairs to the region, even though we have heard that the USA and France have obstructed this. Moreover, the convention on massacres, which should be invoked now in view of the massacre of the Halabjah people, has not been invoked. The Secretary General should work on that. Also, he has not displayed the necessary decisiveness as far as the war of the cities is concerned and as a duty that he shoulders. At any rate, we will send someone to the UN."

Finally, an IRNA reporter asks, "Mr. Hashemi-Rafsanjani, despite the visit by my foreign colleagues to the fronts, as well as to Tehran hospitals, the Iraqi ambassador in London alleged last night that it was Iran that chemically bombed Halabjah. In your remarks, Your Excellency referred to a document on this. Is this a written document? Will you publish this document? Or was it heard from the POWs?" Rafsanjani replies, "We will study the document. If its publication is not contrary to military interests, we will publish it. As for the allegation by the Iraqis, this is extremely ridiculous and impudent. Now the Western correspondents are in our country. They have met the victims of the war, the victims of the chemical war in Halabjah. The interesting point is that we granted permission and told the Halabjah people that anyone who wants to go to Iraq can do so. But none of them [were] prepared to do so. Our proposal still applies. Any of the Iraqi people who have come recently to Iran from Halabjah and that region will be handed over to the International Red Cross if they want to return to Iraq. Our revolutionary guards, too, were poisoned by chemicals. Some of them were martyred, too, beside the Halabjah people. Let the correspondents and the experts see the films shot before the bombing. Iraq has made the same allegation before. UN experts came and stated that Iraq was lying. This time, too, Iraq is opposing their coming. Documents are so strong and clear that there can be no doubt. Well, Iraq is used to perpetrating crimes and refuting them, and it lacks the courage to take responsibility for its crimes. Unfortunately, it has the ear of its mentors, and this stems from the absence of conscience among these mentors. It is interesting and it should be interesting for you to know that we stopped the operations and our advance in order to save the oppressed people of the region. We deployed our hospital facilities, our helicopter transportation and other facilities, to save the people, and we were able to save several tens of thousands of people between 30,000 and 40,000 people from the region, bringing them into Iran. Ask Iraq what it has done to protect its own people."

In its lead article, The Guardian reports on a news conference given by the Iraqi ambassador to London and casts doubt on the claims he made that Iran, not Iraq, was the culprit in the Halabja CW massacre. The paper reports that "we are somewhat better placed than the ambassador to assess the likely origin and effects of the bombing because our own David Hirst was in a group of western reporters taken to Halabja this week by Iranians....Unfortunately for [the ambassador], the only participant in the Gulf War shown by repeated UN investigations to have used chemical weapons is Iraq. Iran did announce last December that it had begun to make 'sophisticated offensive chemical weapons.' But there is no evidence that it has yet done so....Even the Iranian leadership is not eccentric enough to liquidate its own supporters on its most promising front, where its ground-forces and their allies have the Iraqis on the defensive over a wide area."

The Guardian reports that "there is little doubt that the Iranian and Kurdish versions of the tragedy are essentially correct....The attack on Halabja comes in the wake of persistent Kurdish claims that dozens of villages and towns have been attacked in this manner over recent years. Kurds on the Iranian side have not been spared; 100 people died and 2,000 were injured in an Iraqi attack on the Iranian border town of Sardasht on 28 June 1987, according to Iranian reports, and several nearby villages suffered further casualties in fresh attacks this week....Iran announced late in 1986 that it had developed its own chemical warfare technology, and was awaiting a political decision because Iran's war is ideological; I want to 'set an Islamic example' and win over fellow Moslems, especially those in Iraq. Iran's self-proclaimed principles are likely to be severely tested in the coming months, particularly if its troops make further inroads into Iraq."

Reuters reports that during a tour of Halabja, its reporter notes that Iranian officials and local survivors claim that Iraqi forces repeatedly bombed the town with on 16 March, one day after Iranian forces took the town, and that the Iraqis also used CW against the towns inhabitants. Iranian doctors report that the wax-like appearance of some of the dead indicates cyanide poisoning. [Note: This reported condition of corpses at Halabja seems to have formed the basis for the claims that cyanide was used. In fact, this condition is not pathognomonic evidence for cyanide intoxication.]

In the neighboring village of Anap, more bodies were strewn across the town, hanging out of cars and lying on the street. Some of the bodies had turned black. An Iranian Revolution Guard spokesman reports that "the Iraqis, using planes and artillery equipped with chemical weapons releasing mustard gas, cyanide and other types, caused 5,000 innocent people of Halabja and the area to die." According to Reuters, "some survivors said a single warplane appeared from the west at 2 p.m. last Wednesday [16 March] and dropped one or more chemical bombs that dispersed a deadly yellow-and-white cloud. A middle-aged man, one of the handful of people still living on the outskirts of the town, told reporters, "The Iranians came here and we welcomed them. Then, about noon time, the [Iraqi] bombardment came. Everybody was killed. I saw a cloud. I saw gas." Iranian military officials told Western journalists that two Iraqi pilots, whose jets were shot down during the battle, had acknowledged Iraq was responsible for the chemical attack.

The UN states that it is organizing a two-man team to investigate Iraq's use of CW in the Kurdish communities along the Iraq-Iran border. Iran's UN ambassador denounced the international body for slowly responding to the charges of massive CW attacks by the Iraqis. He states that unless the UN sends a team to investigate, Iran will unlikely participate in any UN efforts to end the war. "It means if the United Nations remains inactive regarding all aspects of the war, a political solution would be more and more difficult. We are losing time. Yet not all chances have died. We sincerely hope the United Nations would somehow rectify the inactiveness." In talks later in the day with the Secretary General, the ambassador states that a UN team will arrive in Iran on Monday."

"We are waiting to see what those who were supporting him in the UN Security Council, who used to say, 'Iraq is in favor of peace,' 'Iran is not accepting the resolution and Iran should be boycotted,' and' Iraq be left free are going to do.' Can they wipe the shame off their faces? Will they say the same things after these chemical weapon attacks, after such extensive attacks against cities? We must also praise and thank the correspondents who have come and reported these events. However, unfortunately we have to ask them what they have done since they came and observed this. They say that they have sent photographs and reports, showed the bodies, gone to hospitals, you visited the wounded and heard their moans. You saw the area, you saw the greatest calamities and crimes and what did your governments say? 'We are sorry!' Another one said, 'We are concerned!' The one who has shown the strongest reaction said, 'I condemn this.' The biggest of the lot said, 'I strongly condemn this!' Is that all?

He also states that many of the victims have the types of blisters associated with mustard. An Iranian doctor states that protective gear in the hands of the Iranian forces in the area protected them from most of the CW. Around 300 CW victims are receiving treatment in Tehran hospitals.

Tehran Home Service comments on the recent statement by the UN Secretary General that accused Iraq of carrying out the CW attack on Halabja. After reiterating the Secretary General's belief that there is serious and considerable evidence proving that Iraq committed the atrocity, the report draws attention to diplomatic sources that "believe the UN Secretary General's statement focuses on three important points. First, the Secretary General has raised the issue of the use of chemical weapons by the Zionist Iraqi regime for the first time as an independent issue....Second, for the first time the Secretary General names Iraq specifically and holds the regime ruling in Baghdad responsible for the use of chemicals weapons. Third, he has condemned the use of chemical weapons. Notwithstanding all this, the statement falls short of international expectations by a large margin, and the UN Secretary General's duty remains unchanged."

Iran's Ambassador to the UN states during a press conference that Iraq's recent CW attacks struck not only Halabja, but also towns and villages in Iran. He states that a failure to act on the part of the UN would not only result in the disappearance of the evidence that the crime ever took place, but also it would encourage the Iraqi regime to commit similar crimes in the future. After a meeting with the Secretary General, the ambassador states that Iran believes that the UN team's trip to investigate the attacks, and the report that follows, will certainly inform global opinion about the crime. Iran also hopes the trip and the report will have a practical impact in preventing future CW attacks.

Rafsanjani sends a message to parliaments around the world asking them to condemn the "massacre" at Halabja.

Chief Justice Musavi Ardebili sends a letter to the UN Secretary General stating, "The silence maintained by international circles and the irresponsible attitude of the UN Security Council has become a source of surprise to the freedom-lovers of the world and is an illogical position that contravenes legal precedents and international regulations." Although the Chief Justice thanks the Secretary General "for his action in condemning the Iraqi regime and the dispatch of a UN delegation to experts to review the dimensions of this calamity, [he demands] the legal punishment of the perpetrator of this crime and an arms embargo against the Iraqi regime in addition to a ban against the export of chemical and bacteriological weapons to Iraq or their production in a number of Iraqi cities."

Then, in scenes filmed from a distance, it is possible to see explosions followed by large dispersals of white gas clouds as they cover huge sections of the city. The film concludes by showing another tour of the city, this time filled with dead bodies. Iran claims it films all of its battles and deposited this film with the UN as official evidence. In other news, reports suggest that Iran is unhappy with the composition of the team the UN sent to investigate the recent CW attacks. Consisting of just a political officer and a medical doctor, the team did not have any chemical weapons specialists.

Velayati continues by stating that by attacking Halabja with CW more than 20 times on 17 March, the bombardment was the worst of its kind since the First World War. "Halabja was not the first city subject to Iraqi chemical bombardments, but with 5,000 martyrs and 7,000 injured, 75 percent of them women and children, it was the worst of it." He goes on to state that Iraq first began to use CW in January 1981 and later expanded its use in 1984. He accuses the US and other influential states of having a pro-Iraq policy that has prevented the UN from taking the strong measures necessary to deter Iraqi CW attacks.

He urges the delegates to travel to Zurich and Lausanne to visit the injured receiving treatment there and states that the attack on Halabja "must be recorded as a genocide and crime against humanity....Only, and I repeat only, by practical and unified action can we prevent the repetition of such crimes. No measures were (previously) taken by the Council and as a result Iraq, with open hands and with the hope that there would not be much international reaction, subjected Halabja to its chemical attacks."

In a live television interview in Iran, Velayati updates viewers on recent diplomatic events at the Conference on Disarmament. He states that much of his speech concerned the Iraqi use of chemical weapons in Kurdistan. He informs viewers that he showed films and distributed brochures and pictures to the delegates attending the meeting. When asked what the response was to his speech, Velayati replies, "So far, Austria, the FRG, Great Britain, Switzerland, and the USA have agreed to take the victims of attacks by chemical weapons for treatment. Sweden, Norway, and Spain have expressed their willingness to accept the injured. Belgium has sent a team of physicians to Tehran. The Red Cross has sent a medical team and a planeload of pharmaceutical products. Other consignments of medicines and doctors have been sent. The world mass media, for example, French television, as well as the television networks of Switzerland, Germany [not further specified] Sweden, Australia, Austria, Great Britain and other countries have been presenting detailed coverage of issues pertaining to the use of chemical weapons by the Iraqi regime. At the disarmament sessions during the past few days, Japan, on behalf of the Western countries, condemned the use of chemical weapons, while the GDR denounced Iraq's use of these weapons on behalf of the socialist countries. Sweden independently adopted a categorical and firm stance against the Iraqi regime for its use of chemical weapons. The Australian Foreign Minister declared a strong and firm stance against the Iraqi regime for its use of chemical weapons. For the first time in recent years, the Soviet representative condemned the use of chemical weapons against civilians, as did various other countries, some of which I have already mentioned. general, it appears that despite attempts by the imperialist mass media to ignore this topic, this war crime, and to remain silent about it, the catastrophe was on such a large scale and our brothers in the Islamic Republic made such sincere efforts in this regard that this issue has generated an extensive reaction on the international level. The use of chemical weapons has left an unpleasant impression on people's minds and led to a kind of loathing of the Iraqi regime on the part of people throughout the world. This loathing is now widespread. We can say that the people of the world are coming to the conclusion that the Islamic Republic was justified in saying that as long as the criminal regime remains in the region, the region will not know any peace."

Tehran Home Service reports on a statement made by an Iranian foreign ministry spokesman denouncing recent US allegations that Iran also used CW in Halabja: "The USA's officials, by linking the Islamic Republic of Iran with this false accusation, have sprung to Iraq's assistance so as to weaken and divert the world current [Persian: jarian], which has been built up against Saddam's regime. The foreign ministry spokesman added, "It is disgraceful for the US ruling circles in order to justify their incorrect policy of siding absolutely with Iraq, and now that the regime which they support, even according to the admissions of impartial medical missions and Western mass media, has committed the worst war crime of the present century to resort to such fabrications."

While strongly rejecting the USA's accusations, he added, "The US officials justify the crimes of Iraq in Halabjah, and this move on their part is a green light to that criminal regime to continue its extensive use of chemical weapons. In reality, American military experts are performing a task for Saddam which Goebbels performed for Hitler!...If the USA does not use its influence to compel the Iraqi regime not to repeat a tragedy such as that in Halabjah and not to use chemical weapons, there will be no doubts in the minds of the Iranian nation and all Muslims and freedom-seeking people of the world that the policy of using chemical weapons on the part of the Iraqi regime enjoys the full approval of the USA and that the White House and the war ministry [Defense Department] of the USA too are responsible for and are partners in this war crime as much as Saddam's regime is."

Iran's deputy foreign minister states during a press conference that Iran will be adding new conditions that will need to be fulfilled if it is to accept a cease-fire proposal: namely, that the Iraqi regime be held accountable and punished for its attacks on civilians and its use of chemical weapons. "I think the war of the cities and the use of chemical weapons is not justified at anytime...it is a war crime." He states that the UN needs to strongly condemn these actions and take punitive measures against Iraq such as employing an embargo on shipments to Iraq of chemical weapons precursors. He states that Iraq supports a global ban on the use, storage, and production of chemical weapons; although he does not state that Iran will never use chemical weapons. In response to the US accusations that Iran used chemical weapons against Halabja, he states that the United States is "very naïve" and that the accusations were nothing more than an attempt to "justify American support for Iraq."

IRNA reports, "Foreign Minister Ali Akbar Velayati categorically rejected Baghdad's baseless claims that Iran had used chemical weapons against Iraqi forces. In a letter to the United Nations Secretary General, Velayati expressed surprise that Javier Perez de Cuellar has responded positively to the untenable Iraqi request for dispatch of a UN team to Iraq within 24 hours, while it took more than two weeks for the Secretary General to respond to serious and repeated request by Iran regarding a far graver situation. [The] Iraqi regime, in a vain attempt to divert the international public opinion from Iraqi genocide in the city of Halabjah and in the Qara Dagh region, where Iraqi civilians were targets of chemical warfare by the Iraqi war criminals, has called on the UN to send a team to Iraq. In addition to conducting on-sight investigation of the extent of this latest Iraqi war crime, the team can indeed provide the urgently needed, and till now unavailable, emergency medical warfare in the Qara Dagh region."

Velayati concluded the letter by saying, "in view of the repeated use of chemical weapons in increasingly alarming proportions by Iraq, it is necessary that this investigative endeavour of the Secretary-General lead to a binding and enforceable decision on the prohibition of the use of chemical weapons. It is imperative that the parties commit themselves to accept and abide by such a binding decision."

10 April 1988
US military experts and government officials discuss the growing military challenges in the Middle East. These experts cite the growing use of chemical weapons by both Iran and Iraq—even against civilians. The experts reveal that US intelligence sources first detected Iraqi use of chemical weapons in 1982. That release backfired when poor deployment caused the chemical weapons to drift back over the Iraqi forces. After that experiment, Iraqis used chemical weapons in Kurdistan in 1983, and along the southern front in 1984-85. They state that Iraq has focused its efforts on persistent weapons such as mustard gas rather than non-persistent weapons such as cyanide. This is because the Iraqi military is often on the defensive and wants chemical weapons that will stay in the environment for a long time in order to hold off Iranian attacks for greater periods of time. On the other hand, because Iranian troops are often on the offensive, they have concentrated on non-persistent weapons that will dissipate quickly in front of advancing forces. These weapons include cyanide and chlorine. Pentagon sources state that there are "strong indications" that Iran also used chemical weapons in Halabja. "There is ample reason to believe both had a hand in it. It wasn't a one-way show," the official says.

He guesses that 20-25 Iraqi planes, each carrying 3-4 "special bombs," attacked the Halabja area in mid-March. He denies that he dropped any chemical weapons on Halabja, but admits to dropping chemical bombs near Basra in 1983.

12 April 1988
The Christian Science Monitor reports an interview with Iran's Deputy Foreign Minister that took place sometime last week. In the report, the official states that although the treatment of Iranian soldiers in US hospitals is a positive sign for the troubled relations between the two countries, the recent allegations made by the US State Department about Iranian use of chemical weapons were less positive. In referring to the allegations, the deputy foreign minister states, "They are very negative things. [This is] very open help for a criminal aggressor, which doesn't enjoy any international reputation or credibility. The hostility of American policy toward our revolution is mainly leading the administration to take these kind of positions." The reporter then asks him to comment on a statement made by Iran's foreign minister that although Iran has the capability to use chemical weapons, it has not and will never use chemical weapons. The reporter asks if this can be construed as a formal pledge not to use chemical weapons. He responds, "It is true. This is our position. But there is a main question: what kind of deterrent should we use to prevent Iraqis from using chemical warfare? There are only two, political and military....Unfortunately, the Security Council is showing deaf ears to all the calls, showing inconceivable ignorance...so we are entitled to think of deterrent measures because the political deterrent activities are not enough. But what Dr. Velayati said, it is our constant policy. It is like a country who has the nuclear capability but he wants not to use it at all: as a deterrent measure maybe they have the capability but they are not going to use it."

A high-ranking US official states, "It looks like Iran used its chemical weapons against military targets, while Iraq used them against troops and civilians" in the battle around Halabja last month. US officials state that they have solid intelligence that points to Iranian targeting of Iraqi troops through cyanide-filled artillery shells at about the same time as the gas attack on Halabja. This disclosure is weakening the Iranian propaganda campaign the officials say. US officials have also learned that West German technology and supplies are important to both Iranian and Iraqi chemical weapons arsenals. One example is ammunition-making technology supplied by Fritz Werner, a German tool-making company. US intelligence believes this equipment, supplied to both Iran and Iraq in 1986, has been used in chemical weapons programs.

He disputes claims that Iran has already used chemical weapons, claiming that Iran would be brave enough to admit their use if it ever came to that. He then criticizes the major world powers for maintaining chemical weapons stockpiles and contributing to Iraq's chemical weapons program. He states that although the superpowers are hypocrites for condemning the Iraqi attacks, there words are meaningless and they are simply telling lies.

The paper further reports that many of the city's residents are nervous of attack and that many have made gauze masks filled with [baking] soda.

Iran's UN Envoy sent a formal request to the United Nations in response to its reports of Iraq's use of chemical weapons in recent days. The request was issued "in connection with the renewed use of such weapons against our country's non-military areas. We request the renewed and immediate dispatch of an UN expert delegation in order to investigate the resumed use of chemical weapons by Iraq, and we hope that this time the secretary general will act without delay or hesitation. We must at the same time reiterate that Iraq's increasing use of chemical weapons and the colorless and ineffective reaction of the UN has created yet another worthless round to the advantage of Iraq and against the international community which has lasted since 1984, that is since the time of the dispatch of the first UN expert delegation to the Islamic Republic of Iran."

He continues to state that the Security Council's silence on the topic of Iraq's use of chemical weapons has encouraged further Iraqi use of the weapons. He states, "for quite some time, the Islamic Republic of Iran has predicted the worldwide dangers of the quantitative and qualitative expansion of war crimes and of Iraq's violation of international regulations and it has given the necessary warnings to the UN Secretary General. But unfortunately, the inaction of that organization has consistently left the path open to Iraq." He adds that Iran hopes the next delegation will comprise enough experts to carry out a comprehensive investigation.

Iran's Foreign Minister Ali Akbar Velayati states, "the people of the world have realized that the aggressive Iraqi regime has used chemical weapons against our people, the Iraqi nation, and the Kurdish population. Recently the Arab-populated border villages of the Islamic Republic of Iran in Susangerd and Hoveyzeh were chemically bombed by Iraq. This issue should be pursued seriously at international forums, especially at the Geneva disarmament talks. Many countries and international organizations have already condemned this action."

It's a matter of survival for us. We are not confirming or denying it—but definitely we are not denying it." Iranian officials refused to comment on the report. The team did not visit Halabja, nor did it gather weapons fragments. However, the team was shown shrapnel from bombs dropped on an Iranian village that bore Cyrillic markings.

Iran's UN Envoy Mahallati issues Iran's first formal response to the UN regarding the report that was issued two days ago from the chemical weapons fact-finding mission. It is "very disappointing to note" that the report "fails to address the crime in a clear and unambiguous tone." The mission "did not have the scientific or practical expertise to determine the source of responsibility." Because of this, Iran asks the UN to dispatch "a complete team capable of determining responsibility for the crime." He further requests that the UN "establish a permanent team in Tehran and Baghdad to investigate the extent of and responsibility for future uses of chemical weapons. It is long overdue, with unforgivable consequences, for the Security Council to take effective measures to compel the war criminals in Baghdad to respect internationally recognized rules of warfare." He then urges the Security Council to "condemn Iraq for its continued and persistent use of chemical weapons" and to "impose an embargo on the export of the material and technology for production of chemical weapons to Iraq."

During an interview later that day with the Voice and Vision of the Islamic Republic, Mahallati declares the UN report to be defective and criticized its delay. He states, "the unjustified delay of the UN Secretariat in releasing this report gave the Iraqi regime a chance to use chemical weapons again after its deployment of such weapon in Halabja....In spite of the clear admission by the fact-finding mission stressing that chemical weapons have been used more extensively and more seriously, the stances of the UN Secretary General in its connection appears to be insufficient....The least the UN can do is to condemn the Iraqi regime for the deployment of chemical weapons, ban any export of chemical materials to Iraq which can be used to manufacture chemical weapons and establish a permanent supervisory mission on the deployment of chemical weapons in the region."

The production of gas masks for fighting chemical weapons has begun at Iran's National Industries Organization's Yasa factory. The director of the Yasa factory states, "Anti-chemical gas masks for war are a strategic product produced in a limited number of countries. Because they are a strategic product, their production is extremely difficult. However, a long time ago the IRGC [Iranian Revolutionary Guard Corps] brothers assigned Iran Yasa the duty of testing and producing this mask. Fortunately these efforts proved fruitful and these masks are now being produced in limited numbers. In addition to ending our dependence, we will also be saving large amounts of foreign currency. The final price of the masks is one-eighth the cost of imported masks."

During the Friday prayers at Tehran University, Rafsanjani states that, "What the UN did recently was very strange. During the Halabja incident, the majority of the world media, the majority of international correspondents, and the majority of doctors who became involved and all the experts who came, all explicitly expressed the view that Halabja was a crime committed by Saddam and that Saddam had resorted to genocide there. The most responsible authority associated with the UN sent an expert. Then after a delay of 40 days, during which the case was somewhat stalled, it said in a weak statement that, yes, in Halabja, chemical substance had been used and that individuals from Iran and Iraq had been hurt....That is how impotent they are in front of this revolution and this Islam that they whitewash an obvious fact, which all the world can see."

Iran's deputy foreign minister criticizes the UN decision not to send a complete team to investigate the use of chemical weapons by Iraq. This decision, which he claims appears to have been a plot from the very beginning, led to the filing of an incomplete report that failed to name Iraq as the perpetrator of the chemical weapons attack. He states that the attack on Halabja was an "unprecedented massacre" and that if punishment for the crime was not effectively meted out, the use of chemical weapons will become commonplace throughout the world. He states that Iran would prefer that the major powers would exercise their power and compel Iraq to cease its use of chemical weapons. If they do not, Iran will be forced to consider compelling Iraq through military means.

During a program called the "Political Round Table" aired on the Voice and Vision of the Islamic Republic of Iran, the moderator of the program poses a question: At the beginning of this week on Saturday, Mr. Hashemi-Rafsanjani talked about preventing Iraq from continuing the war of the cities and chemical attacks. He said that a good deterrent would be more extensive retaliatory operations, at an even greater level than the Iraqi attacks....Is this change in policy due to the UN expert's report, which was extremely tepid and did not condemn Iraq as it should have, or is it due to Iraq's increasing use chemical attacks at the front, such as in Halabja?" In response to this question, Iranian Deputy Prime Minister Ali Reza Mo'ayyeri states, "Of course, we have had the capability to produce chemical weapons and use them for years, but we have not done so....International organizations, and the UN in particular, have unfortunately not adopted a strong and firm stance to prevent the use of these weapons....With its dispatch of a very inadequate two-member team, who were not even experts in chemical weapons, a vague report was prepared and then presented to the UN Security Council....As regards the retaliatory tit-for-tat operations, we have never used chemical weapons, despite our capability to do so. We will endeavor to maintain our restraint in this regard, but restrain and patience have a time limit, too. If the aggression continues, we shall use our resources."

The moderator then asks the acting chief of the IRGC GHQ, Abbas Mohtaj, "What role do chemical weapons play on the fronts and in operations?" He responds, "The use of chemical weapons depends on the readiness of our forces, and their effectiveness depends on the quantity used. The difference between chemical and conventional weapons is this if a mortar explodes in a battalion, some will be wounded, some martyred; with chemical weapons, a great number will be affected and hurt....But I must add that chemical weapons can never be the deciding factor in any war. They can only serve to slow down or half movements at various stages."

1. Affirms the urgent necessity of strict observance of the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare, signed at Geneva on 17 June 1925;

2. Condemns vigorously the continued use of chemical weapons in the conflict between Iran and Iraq contrary to the obligations under the Geneva Protocol;

3. Expects both sides to refrain from the future use of chemical weapons in accordance with the obligations under the Geneva Protocol;

4. Calls upon all States to continue to apply or to establish strict control of the export to the parties to the conflict of chemical products serving for the production of chemical weapons;

5. Decides to remain seized of the matter and expresses its determination to review the implementation of this resolution.

A Tehran Home Service commentary criticizes the UN Security Council stating that its "ineffective and imperfect stance, more than 50 days after the chemical bombing of Halabjah by the Iraqi criminal regime, showed that the Security Council has so far failed to act in accordance with the UN Charter, based on the Geneva Protocol of 1925, to halt the proliferation and deployment of chemical weapons by Iraq. The Council's long silence in the face of this horrific crime, which was condemned by many countries and personalities including the UN Secretary General, emboldened that regime to repeat its crime and deploy chemical weapons in residential areas of southern regions of the Islamic Republic of Iran [IRI]....It seems that from now on the deployment of chemical weapons will become a normal option and will from this date be added to the war capabilities of many countries....The current resolution of the Security Council on a general condemnation of chemical weapons deployment in the Iran-Iraq War has justified Iraq's action in its inhumane crime at Halabjah, which is unprecedented since the First World War, and has tried to follow the policies of the USA and other Western supporters of Saddam by classifying both countries [Iran and Iraq] in the same category. The objective of this sinister plot of Western imperialism, led by America, is to cover up the Iraqi regime's deployment of chemical weapons so as to realize the plan for imposing an arms embargo against the IRI. This is taking place at a time when the Iraqi regime, in the war against Iran, is constantly armed and equipped by these countries and Arab reaction. At present the release of the Security Council's ineffective resolution on the deployment of chemical weapons, which took place as the result of some Council members' measures of support for the Iraqi regime, has overshadowed [or undermined; Persian: tahtoshshoa] the Secretary General's just stance in condemning this regime and the deployment of chemical weapons....The biased and critical measures of the UN regarding the developments of the Iran-Iraq War, [measures] which are always undertaken in order to encourage the Iraqi regime to continue its atrocities with the co-operation of the USA and Arab reaction, will further familiarize the international community with the bitter taste of the hegemonist powers' desire to serve their own interests....The expansion of these crimes will naturally engulf other countries of the region and the world with its horrific consequences."

He claims Iraq has used chemical weapons 253 times since the beginning of the war and that the worst attack of all—Halabja—was the result of the international community's "indifference and irresponsible attitude." He proposes the establishment of a permanent team of UN chemical weapons specialists in the region, stating that their presence would be an important deterrence against future attacks.

Tehran Home Service reports that Foreign Minister Ali Akbar Velayati has described the indifference of the UN to the chemical bombing of Sardasht as the cause of the heinous atrocity subsequently perpetrated by the Iraqi regime in Halabja. He warned the people of the world that the latest Security Council stance on this crime will soon result in the extensive use of chemical weapons for the annihilation of humanity in all parts of the world. According to the central news unit, Mr. Velayati, who was speaking at the special UN disarmament conference session in New York, gave details of the outcome of the use of chemical weapons by the Iraqi regime in Iranian residential areas. He said that the banning of chemical weapons was the most important obligation of the disarmament conference, and called on the session to take a stand against this dangerous international phenomenon, pointing out that the UN is the most appropriate and suitable organization to do so. He called on the Security Council to carry out the necessary study for the implementation of Resolution 612 and to take a firm stance against the Iraqi regime's indifference to the contents of this resolution and its repeated use of chemical weapons [only] 10 days after the approval of this resolution. He asked the Council to refrain from mere slogans and abandon its inertia.

Regarding the silence of the UN on the crimes of the Ba'thist Iraqi regime, Velayati said, "With immense audacity, Iraq continues its use of chemical weapons as part of its proclaimed policy in the imposed war....it is hoped that, in view of Iraq's insistence on using such weapons, and its acknowledgement of their purchase and use, the UN Security Council will condemn Iraq directly and vehemently and take immediate, decisive and drastic steps to ban the sale of materials for producing chemical weapons and to inspect chemical installations in Iraq."

He states, "Bearing in mind the need to observe the Geneva Convention prohibiting the production and deployment of chemical weapons, Iran condemns any use of such weapons. It considers that the immediate closure of all chemical weapons factories is in the interest of mankind and [is] an urgent and undeniable duty....If the international organizations continue their silence in the face of the crimes and atrocities of the Iraqi regime, which is tantamount to collaborating with it, the adverse, unknown and escalating consequences of the widespread use of chemical weapons will affect mankind all over the world, and few societies will be safe from them. To perform their international duty, governments should not only refrain from selling any material which could be used for this purpose or placing it at the disposal of others, but they should supervise the operation of companies and factories which prepare and supply raw materials which could be processed into chemical weapons, so that the profiteering and power-seeking ambitions of individuals or regimes which disregard humanitarian commitments, would not encourage them to produce and use materials deadly to mankind..."

A commentary on Tehran Radio states, "At that time the authorities of the Islamic Republic reminded the UN that a failure to confront decisively in international forums these inhuman acts by the Iraqi regime would embolden that regime in the use of chemical weapons. Thus, before long the correctness of the predictions of the Islamic Republic was proved. The Iraqi regime then extended the domain of its chemical attacks to the towns and in so doing it brought about a calamity such as that in the town of Halabja martyring 5,000 residents, mainly women and children, using chemical agents. After the Halabja calamity, the UN was forced to approve Resolution 612 in an independent form for the purpose of prohibiting the use of chemical weapons in the imposed war. Yet, despite the approval of this resolution, so far no efforts have been made to implement it."

Upon the announcement of this decision, we expressed our surprise at this hasty decision, which was based on an arbitrary interpretation of the informal consultations of the Security Council on this subject. After the decision to dispatch the team was made, the permanent representative of Iran notified the secretariat that his government was not ready to receive the mission. This development confirms beyond any doubt that the Iranian authorities do not have the evidence to back up their allegations and fabrications, which coincided with Iran's military defeats on the battlefield in recent months. It also confirms beyond any doubt that the secretariat was once again hasty in responding to unsubstantiated Iranian allegations and lies."

Velayati responds, "This invitation was issued a few weeks ago. On a number of occasions after the ratification of Resolution 612 in connection with Iraq's use of chemical weapons, the Iraqi regime repeatedly used chemical weapons against us. We repeatedly reported this to the UN and requested that, in accordance with the Security Council's approval, the Secretary General should dispatch missions to inspect the locations and investigate the effects of the weapons used immediately upon receiving reports of the contravention of an agreement such as the use of chemical weapons here which is an overt contravention of the recent Security Council resolution. Unfortunately, a few weeks passed and the Security Council delayed sending a delegation; therefore, most of the traces of the use of chemical weapons by the Iraqi regime have been destroyed. This procrastination and delay definitely have political reasons; that is, Iraq's protectors have influenced the [UN] Security Council....But, in any case, the sending of missions to investigate the use of chemical weapons by Iraq could have positive results.

The Iraqis, explained a revolutionary guard, saturate the frontlines with quick-acting poisons such as nerve gas and the rear with a slow-acting one, mustard gas. It appears to be a formidable combination, its effects all the more extraordinary in that it is the revolutionary guards who, if not actually running away, are abandoning desperately and expensively won positions with barely a fight...each Iraqi success seems to have an incremental effect; just how low morale has sunk became clear last week when rumors sweeping the capital had it that, under a colossal chemical bombardment killing tens of thousands of people, Khorramshahr had fallen to the Iraqis—the same Khorramshahr which was renamed Kuninshahr, 'City of Blood,' as the prime symbol of heroic, popular resistance to the original Iraqi onslaught."

UN teams from 1984 have repeatedly evidenced Baghdad's use of poison gases culminating in the massacre of over 5,000 Kurds at Halabja in March this year, but save a presidential statement, the Security Council has yet to condemn the Iraqi regime for its persistent violations. The present resolution does little more than 'deplore' the invitation of the conflict, the attacks of shipping and civilian targets and the use of chemical weapons, but gives the Security Council an opportunity to redeem itself from its ignoble past. If and when implemented to the letter, the Security Council Resolution 598 on [the] Iraq-Iran War seems capable of paving the way for peaceful settlement of the conflict."

Iran claims Iraqi forces have moved across large sections of Iran and bombed the villages of Sar-e Pol Zahab and Gilan-e Gharb with chemical weapons. The chemical attacks are said to have injured "a large number of villagers." Gilan-e Gharb, 20 miles inside Iran, fell under the weight of a chemical attack. "The aggressors also captured Sar-e Pol Zahab garrison using the same dastardly tactic."

Sadegh Tabatabai, a member of Iran's Supreme Defense Council, tells the German periodical Stern that Iran has dropped its preconditions that Iraq be named as the aggressor during the war and agreed to begin cease-fire negotiations under UN Resolution 598 which passed 20 July 1987. Tabatabai explains that the main reason Iran gave up its precondition was due to Iraq's use of chemical weapons. "We did not want to counter the massive use of chemical weapons with a similar action. Therefore, we decided to do the responsible thing and accept something dreadful so that something still more dreadful would not happen."

Tehran Radio reports that, according to a Central News Unit report, sources close to the Security Council state that Council members are angered over Iraq's use of chemical weapons. According to the report, some members of the Council have warned that further silence by the UN will leave a bad historical precedent. Tehran Radio goes on to state that the British envoy to the UN states that all members of the Security Council agree that the use of chemical weapons has been the most terrible aspect of the Iran-Iraq War. UN sources, according to Tehran Radio, "have stressed that the 15 members of the Security Council have been really scared by reading the report [written by the team investigating chemical weapons use by Iraq], not yet published, concerning the use of chemical weapons by the Iraqi regime." UN diplomats have stated that now there is now doubt amongst members of the Security Council that Iraq has clearly violated the 1925 Geneva Convention.

1 August 1988
Two UN Security Council investigators publish a report that the Iraqis have been using chemical weapons in the Iran-Iraq War. From their examination of Iranian victims, weapons fragments and soil samples, and from seven previous UN reports, the authors conclude that the Iraqis have been using chemical weapons (including mustard gas, two types of nerve gas, and cyanide gas) with increasing intensity and frequency against Iranian troops and civilian targets since 1984. This report neither condemns nor clears Iran on charges of also having used chemical weapons. Iraqi produced nine gassed soldiers and grenades captured from Iranian soldiers to prove Iran's use of chemical weapons, but the report's wording leaves open the possibility that the grenades were Iraqi and the soldiers were injured when handling their own side's weapons.

1 August 1988
Excerpts of the United Nations report issued on this day:

"We deeply regret to say that, on the basis of evidence gathered during the present mission, and in spite of repeated appeals by the United Nations, chemical weapons continue to be used on an intensive scale against Iranian forces. As highlighted...by previous missions to Iran, the continued use of such weapons in the present conflict increases the risk of their use in future conflicts."

"The use of yperite (mustard gas) was again confirmed, both medically and by chemical analysis....The use of nerve gas or cyanide was not confirmed by chemical analysis in the field, no doubt owing to their rapid disappearance....According to patients as well as reports of doctors,...2,000 people had been affected on the Majnoon Islands....The chief of the medical service of the region further said that, on June 25... there had been a massive attack by Iraqi forces which had begun with artillery fire using chemical ammunition and lasted for approximately two hours."

"From the examination of weapon fragments it can be concluded that bombs similar [to those] in 1984, 1986 and 1987 have again been used against Iranian forces on Iranian territory, indicating their repeated utilization by Iraqi forces."

"On July 11, the team visited the camp outside Baghdad. After donning protective equipment supplied by the military authorities, as some grenades in the stockpile were leaking and were in bad condition, we went into a bunker containing 81mm mortar grenades. The number of grenades was stated to be 141, and they were claimed to be chemical munitions captured from Iranian forces in Salamcha, east of Basra....Unopened grenades still in wooden crates were tested....A positive response was obtained, suggestive of the presence of a blister agent."
