Background

This page is part of the Iraq Country Profile.

Iraq first developed a chemical weapons capability in the early 1960s. During the Iran-Iraq War, Iraq used tabun and mustard gas on a large scale against both Iran and the Kurdish populations in northern Iraq. Iraq’s chemical weapons program was dismantled under United Nations Security Council Resolution 687, following Iraq’s defeat to coalition forces in the First Gulf War. However, the United States and others remained concerned that Iraq had reconstituted its WMD programs, including its chemical weapons program. The 2003 Iraq War was launched on this belief. However, the post-war survey of Iraq’s WMD activities (known as the Duelfer Report) found that Iraq’s chemical weapons program had been successfully dismantled, although evidence suggested that the Iraqi government had hoped to reconstitute the program in the future. Iraq acceded to the Chemical Weapons Convention (CWC) in 2007.

History

Failure and multiple bureaucratic reorganizations marred initial Iraqi efforts to develop chemical weapons The Iraqi Chemical Corps began research and development into chemical weapons in the 1960s and attempted to synthesize small quantities of chemical warfare (CW) agents, including mustard gas and tabun. [1] These initial attempts failured, and the Iraqi Intelligence Service (IIS) took over responsibility for chemical weapons research, founding the al Hazen ibn al-Haiteham Institute in 1974. [2] However, by 1978, the IIS also had failed to develop CW agents, due in part to extensive mismanagement. The al Hasan foundation was abolished as a result, and the Iraqi Chemical Corps again took up responsibility for the program. [3]

The 1980 Iran-Iraq War gave new impetus to chemical weapons research. In June 1981 Iraq founded Project 922, within the Ministry of Defense, to oversee development and production. [4] Project 922 drew much of its equipment and expertise from the al Rashad laboratory complex of the al Hazen Institute, and was able to produce tens of tons of mustard gas by 1983. [5] Project 922 continued to expand in size and scope, and by 1989 had produced several thousand tons of CW agents, including mustard gas and two different types of nerve agents. [6]

Iraq began using chemical weapons against Iranian troops in 1982. [7] Bombardments began with tear gas and expanded to include mustard gas attacks during the 1983 Val Fajr II campaign near Haj Umran. [8] Over the course of the war, Iraq continued to use mustard gas, tear gas, and eventually the nerve agent tabun. Chemical weapons attacks collectively resulted in over one million Iranian casualties by the end of the war. [9] The Iraqi government also mounted massive chemical attacks against the Kurdish population in northern Iraq. One attack in 1988 on the Kurdish town of Halabja killed over 6,000 civilians. [10]

UN Security Council Resolution 687, passed on 3 April 1991 after Iraq’s defeat in the Gulf War, mandated the complete dismantlement of Iraq’s WMD programs, including the CW program. The resolution also established the United Nations Special Commission (UNSCOM) to oversee the dismantlement process. By December 1998, UNSCOM inspectors had overseen the destruction of 38,537 filled and unfilled chemical munitions, 690 metric tons of CW agents, more than 3,275 metric tons of precursor chemicals, and over 425 pieces of key production equipment. [11] UNSCOM was able to account for the destruction of 88,000 filled and unfilled chemical munitions, over 690 metric tons of weaponized and bulk CW agents, approximately 4,000 metric tons of precursor chemicals, and 980 pieces of key production equipment. [12]

In August 1998 Iraq unilaterally declared that all outstanding CW-related disarmament issues were resolved and ceased cooperation with UNSCOM. This decision led to UNSCOM’s withdrawal in December 1998, followed by Operation Desert Fox in which the United States and United Kingdom bombed a number of facilities thought to have been used in reviving Iraq’s WMD programs.

On 19 March 2003 a United States-led coalition invaded Iraq and overthrew Saddam Hussein. A major justification for the invasion was the U.S. government’s belief that Iraq had reconstituted its CW program. Specifically, the U.S. argued that Iraq had failed to account for 1.5 tons of VX, 1,000 tons of mustard gas, and 550 filled munitions, in violation of UN Security Council Resolution 1441. This was despite findings by the UN Monitoring, Verification, and Inspections Commission (UNMOVIC), the organization that replaced UNSCOM, that there was no evidence of Iraqi continuation or resumption of WMD programs. [13]

In April 2003 the United States tasked the Iraq Survey Group (ISG), headed by former UN inspector David Kay, with locating suspected WMD stockpiles and equipment. However, Kay rejected suggestions that there had been any significant Iraqi WMD activities since the end of the first Gulf War. Former UNSCOM member Charles A. Duelfer later replaced David Kay as head of the ISG.

On 30 September 2004 the ISG released its final report on Iraq’s WMD programs. Its key findings regarding Iraqi chemical weapons programs were as follows:

  • Saddam Hussein never abandoned his intention to resume a CW effort once sanctions were lifted and conditions were judged favorable.
  • While a small number of old, abandoned chemical munitions have been discovered, the ISG judges that Iraq unilaterally destroyed its undeclared chemical weapons stockpile in 1991.
  • The way Iraq organized its chemical industry after the mid-1990s allowed it to conserve the knowledge base needed to restart a CW program, conduct a modest amount of dual-use research, and partially recover from the decline of its production capability caused by the effects of the Gulf War and UN-sponsored destruction and sanctions.
  • Iraq constructed a number of new plants starting in the mid-1990s that enhanced its chemical infrastructure, although its overall industry had not fully recovered from the effects of sanctions, and the country had not regained its pre-1991 technical sophistication or production capabilities prior to Operation Iraqi Freedom (OIF).
  • The ISG uncovered information that the Iraqi Intelligence Service had maintained, from 1991 to 2003, a set of undeclared covert laboratories to research and test various chemicals and poisons, primarily for intelligence operations. [14]

Recent Developments and Current Status


In 2007 the Iraqi government acceded to the CWC following a drawn-out process of deliberations. Since then, there have been no major concerns over new chemical weapons developments; however, continued unrest in the country has created difficulties for routine CWC-mandated inspections by the OPCW.

A New York Times investigation by C.J. Chivers revealed that the dismantlement of Iraq’s CW program was not as clear-cut as originally thought. The investigation revealed that approximately 5,000 chemical warheads, shells, or aviation bombs were recovered following the 2003 Iraq war. [15] Although all of these munitions were produced before 1991, they did pose serious hazards; at least 17 American soldiers and seven Iraqi police officers were exposed to CW agents. [16] A subsequent investigation by Chivers and Eric Schmitt revealed a major CIA-run effort, Operation Avarice, to purchase old chemical weapons that were on the Iraqi black market. The program purchased and destroyed over 400 Borak rockets, many of which contained sarin. [17]

The Syrian civil war has generated concern over the legacy of Iraq’s CW program. In July 2014, the Islamic State (IS), a militant jihadist organization, seized a former Iraqi chemical weapons production facility that U.S. officials believe still contains remnants of Iraq’s chemical weapons arsenal. [18] The last major UN report on Iraq’s WMD programs in 2004 found that the facility contained 2,500 122mm chemical rockets filled with sarin, 180 tons of sodium cyanide, and numerous empty shells and containers contaminated with mustard residue. [19] However, the materials in question date back to the 1980s, and are unlikely to be useful for chemical warfare purposes.

Kurdish and Iraqi military officials claim that IS has used chemical weapons within Iraq, against the Peshmerga forces, multiple times in the past year. Specifically, the Kurdistan Region Security Council has offered video and lab results that it claims prove IS used chlorine gas on 23 January 2015 in a suicide truck bombing. This attack has not been investigated or verified by other independent sources. [20] Additionally, officials believe IS committed chlorine attacks in December 2014 and March 2015, though they do not have test results. Kurdish officials released a video of the aftermath of a similar IS suicide truck bombing on 26 December 2014, which is believed to have involved chlorine gas. The video shows men coughing and pouring water over their heads; 60 men were wounded in the attack. Kurdish forces are investigating the March 2015 attacks. [21]

Glossary

Chemical Weapon (CW)
The CW: The Organization for the Prohibition of Chemical Weapons defines a chemical weapon as any of the following: 1) a toxic chemical or its precursors; 2) a munition specifically designed to deliver a toxic chemical; or 3) any equipment specifically designed for use with toxic chemicals or munitions. Toxic chemical agents are gaseous, liquid, or solid chemical substances that use their toxic properties to cause death or severe harm to humans, animals, and/or plants. Chemical weapons include blister, nerve, choking, and blood agents, as well as non-lethal incapacitating agents and riot-control agents. Historically, chemical weapons have been the most widely used and widely proliferated weapon of mass destruction.
Tabun (GA)
Tabun (GA): A nerve agent, tabun was the first of the nerve agents discovered in Germany in the 1930s. One of the G-series nerve agents, Nazi Germany produced large quantities of tabun but never used it on the battlefield. Tabun causes uncontrollable nerve excitation and muscle contraction. Ultimately, tabun victims suffer death by suffocation. As with other nerve agents, tabun can cause death within minutes. Tabun is much less volatile than sarin (GB) and soman (GD), but also less toxic.
Mustard (HD)
Mustard is a blister agent, or vesicant. The term mustard gas typically refers to sulfur mustard (HD), despite HD being neither a mustard nor a gas. Sulfur mustard gained notoriety during World War I for causing more casualties than all of the other chemical agents combined. Victims develop painful blisters on their skin, as well as lung and eye irritation leading to potential pulmonary edema and blindness. However, mustard exposure is usually not fatal. A liquid at room temperature, sulfur mustard has been delivered using artillery shells and aerial bombs. HD is closely related to the nitrogen mustards (HN-1, HN-2, HN—3).
Dismantlement
Dismantlement: Taking apart a weapon, facility, or other item so that it is no longer functional.
United Nations Security Council
United Nations Security Council: Under the United Nations Charter, the Security Council has primary responsibility for maintaining international peace and security. The Council consists of fifteen members, five of which—China, France, Russia, the United Kingdom, and the United States—are permanent members. The other ten members are elected by the General Assembly for two-year terms. The five permanent members possess veto powers. For additional information, see the UNSC.
WMD (weapons of mass destruction)
WMD: Typically refers to nuclear, biological, or chemical weapons, though there is some debate as to whether chemical weapons qualify as weapons of “mass destruction.”
Chemical Weapons Convention (CWC)
The Chemical Weapons Convention (CWC) requires each state party to declare and destroy all the chemical weapons (CW) and CW production facilities it possesses, or that are located in any place under its jurisdiction or control, as well as any CW it abandoned on the territory of another state. The CWC was opened for signature on 13 January 1993, and entered into force on 29 April 1997. For additional information, see the CWC.
Nerve agent
A nerve agent is a chemical weapon that attacks the human nervous system, leading to uncontrolled nerve cell excitation and muscle contraction. Specifically, nerve agents block the enzyme cholinesterease, so acetylcholine builds up in the nerve junction and the neuron cannot return to the rest state. Nerve agents include the G-series nerve agents (soman, sarin, tabun, and GF) synthesized by Germany during and after World War II; the more toxic V-series nerve agents (VX, VE, VM, VG, VR) discovered by the United Kingdom during the 1950s; and the reportedly even more toxic Novichok agents, developed by the Soviet Union between 1960 and 1990. The development of both the G-series and V-series nerve agents occurred alongside pesticide development.
United Nations Special Commission on Iraq (UNSCOM)
UNSCOM: An inspection and weapons destruction program established pursuant to paragraph 9(b)(l) of UN Security Council Resolution 687 (1991) following the 1990 to 1991 Gulf War. Section C of the resolution called for the elimination, under international supervision, of Iraq's WMD and ballistic missiles with a range greater than 150 kilometers, together with related items and production facilities. It also called for measures to ensure that Iraq did not resume the acquisition and production of prohibited items. UNSCOM was set up to implement the non-nuclear provisions of the resolution, and to assist the International Atomic Energy Agency in the nuclear areas. It was replaced by UNMOVIC in 1999.
Disarmament
Though there is no agreed-upon legal definition of what disarmament entails within the context of international agreements, a general definition is the process of reducing the quantity and/or capabilities of military weapons and/or military forces.
VX
VX: The most toxic of the V-series nerve agents, VX was developed after the discovery of VE in the United Kingdom. Like other nerve agents, VX causes uncontrollable nerve excitation and muscle excitation. Ultimately, VX victims suffer death by suffocation. VX is an oily, amber-colored, odorless liquid.
United Nations Monitoring, Verification and Inspection Commission (UNMOVIC)
UNMOVIC: The successor to the United Nations Special Commission on Iraq established by UN Security Council Resolution 1284 (1999), UNMOVIC was mandated to establish a reinforced, ongoing monitoring and verification system to check Iraq's compliance with its obligations not to reacquire WMD. UNMOVIC was terminated in June 2007. See entry for United Nations Special Commission on Iraq.
Sanctions
Punitive measures, for example economic in nature, implemented in response to a state's violation of its international obligations.
Dual-use item
An item that has both civilian and military applications. For example, many of the precursor chemicals used in the manufacture of chemical weapons have legitimate civilian industrial uses, such as the production of pesticides or ink for ballpoint pens.
Organization for the Prohibition of Chemical Weapons (OPCW)
The OPCW: Based in The Hague, the Netherlands, the OPCW is responsible for implementing the Chemical Weapons Convention (CWC). All countries ratifying the CWC become state parties to the CWC, and make up the membership of the OPCW. The OPCW meets annually, and in special sessions when necessary. For additional information, see the OPCW.
