A 1994 article published by the Israeli Ministry of Foreign Affairs refers to an Iranian missile plant in the city of Farhin. [1] Three years later the London Times identified the plant as a potential target should Israel decide to launch an air-strike against Iran's ballistic missile program. [2] The authenticity of the reports and the existence of the facility are highly questionable. There have been no further open source references to the site since the 1997 news report.
