In April 1991, the United Nations Security Council adopted Resolution 687, which established the terms and conditions for a formal cease-fire between Iraq and the coalition of Member States. Resolution 687 states that Iraq shall unconditionally accept the destruction, removal, or rendering harmless—under international supervision—of all chemical and biological weapons; all stocks of agents, and all related subsystems and components; and all related research, development, support, and manufacturing facilities. The resolution further states that Iraq shall unconditionally undertake not to use, develop, construct, or acquire any of the items mentioned above, and it calls for the development of a plan for ongoing monitoring and verification of Iraq's compliance. To accomplish these objectives, Resolution 687 provided for the establishment of a Special Commission to carry out immediate on-site inspections of Iraq's capabilities, based on Iraq's declarations and the designation of any additional locations by the United Nations Special Commission (UNSCOM) itself. Soon after it was established, the commission initiated a series of unprecedented inspections to eliminate Iraq's weapons of mass destruction.
