Sudan: Chemical Weapons

Question: To ask His Majesty's Government what assessment they have made of the report from the former officials of the Organisation for the Prohibition of Chemical Weapons that they have evidence of use of chemical weapons in the war in Sudan; and whether they intend to raise this in the UN Security Council.

Answer: We are aware of recent media reporting of alleged chemical weapons use in Sudan and are reviewing the allegations carefully. The UK takes any alleged breach of the Chemical Weapons Convention very seriously. Sudan is a State Party to the Chemical Weapons Convention and we expect all those in Sudan to abide by the prohibition on developing, producing, possessing, transferring or using chemical weapons. We have consistently raised serious concerns about allegations of chemical weapon use in Sudan, including at the Organisation for the Prohibition of Chemical Weapons (OPCW), and will continue to do so. Officials have also raised this specific report with representatives of the Sudanese Armed Forces and urged Sudan to conclude its investigation into the allegations and report back to the OPCW.
