On 21 March 1986, the Security Council of the United Nations stated that the Council members were "profoundly concerned by the unanimous conclusion of the specialists that chemical weapons on many occasions have been used by Iraqi forces against Iranian troops...[and] the members of the Council strongly condemn this continued use of chemical weapons in clear violation of the Geneva Protocol of 1925 which prohibits the use in war of chemical weapons" (S/17911 and Add. 1, 21 March 1986). The United States voted against the issuance of this statement.[10]
