. The integration and cooperation between the Iranian Army and various militias allowed them to organize operations during winter 1985–1986 carefully. As a result, Iraq's oil wells were in danger. Iraqi General Hamdani called the fighting for the liberation of the peninsula another "Battle of the Somme", where both militaries suffered huge losses. The chemical attacks played an important role in Iraq's success.
The chemical attacks took place until the last day of war, in August 1988.
During the eight-year Iran–Iraq War, more than 350 large-scale gas attacks were reported in the border areas.

International convention

Because of reports implying the use of chemical weapons by the Iraqi army, a presidential directive was issued by the U.S.
Iran asked the UN to engage in preventing Iraq from using chemical weapon agents, but there were no strong actions by the UN or other international organizations. UN specialist teams were dispatched to Iran at the request of the Iranian Government, in March 1984, April 1985, February–March 1986, April 1987, and in March, July and August 1988. As a result, according to the field inspections, clinical examinations of casualties and laboratory analyses of samples done by the UN fact-finding team's investigations, the use by the Iraqi army of mustard gas and nerve agents against Iranians was confirmed. The

ratified these reports and two statements were issued, on 13 March 1984 and 21 March 1986, condemning Iraq for those chemical attacks, but the Iraqi regime did not abide by those condemnations and continued launching chemical attacks.
The Iraqi chemical weapons program was curtailed in 1991, and the group found no evidence of its work at a later date. After the invasion, Saddam's son Uday tried to find chemical weapons in Iraq and use them against coalition forces, but he failed to do so. The biological weapons program was curtailed in 1995, as it seemed to Hussein that UN inspectors were about to be able to detect it. The arsenal of biological weapons was destroyed back in 1991 and 1992. Only a few copies remained intact, which were preserved in the hope of the future. The production of nuclear weapons was also shut down in 1991. The authorities destroyed all documents related to this program, except for documentation on several projects, which the scientists saved on their own initiative. Thus, the claims of Blair and Bush about Saddam's existing WMD production programs have now been officially recognized as false.
