United Nations Security Council Resolution 620

Adopted by the Security Council at its 2825th meeting on 26 August 1988

The Security Council,

Recalling its resolution 612 (1988),

Having considered the reports of 20 and 25 July and 19 August 1988 (S/20060 and Add.1, S/20063 and Add.1, S/20134) of the missions dispatched by the Secretary-General to investigate allegations of the use of chemical weapons in the conflict between the Islamic Republic of Iran and Iraq,

Deeply dismayed by the missions' conclusions that there had been continued use of chemical weapons in the conflict between Iran and Iraq and that such use against Iranians had become more intense and frequent,

Profoundly concerned by the danger of possible use of chemical weapons in the future,

Bearing in mind the current negotiations in the Conference on Disarmament on the complete and effective prohibition of the development, production and stockpiling of chemical weapons and on their destruction,

Determined to intensify its efforts to end all use of chemical weapons in violation of international obligations now and in the future,


 * 1) Condemns resolutely the use of chemical weapons in the conflict between Iran and Iraq, in violation of obligations under the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare, signed at Geneva on 17 June 1925, and in defiance of its resolution 612 (1988);
 * 2) Encourages the Secretary-General to carry out promptly investigations, in response to allegations brought to his attention by any Member State concerning the possible use of chemical and bacteriological (biological) or toxin weapons that may constitute a violation of the 1925 Geneva Protocol or other relevant rules of customary international law, in order to ascertain the facts of the matter, and to report the results;
