Resolution 620 (1988) of 26 August 1988
The Security Council,
Recalling its resolution 612 (1988) of 9 May 1988,
Having considered the reports of 20 and 25 July and of 2 and 19 August 1988 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 the Islamic Republic of 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 the Islamic Republic of 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 toxic
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;
3. Calls upon all States to continue to apply, to establish or to strengthen strict control of the export of
chemical products serving for the production of chemical weapons, in particular to parties to a conflict, when
it is established or when there is substantial reason to believe that they have used chemical weapons in violation
of international obligations;
4. Decides to consider immediately, taking into account the investigations of the Secretary-General, appropriate
and effective measures in accordance with the Charter of the United Nations, should there be any future use of
chemical weapons in violation of international law, wherever and by whomever committed.
Adopted unanimously at the 2825th meeting.
