Developments: 2. Allegations have emerged suggesting the Sudanese Armed Forces (SAF) developed and utilized a secret chemical weapons program. Leaked intelligence, including approximately 150 military documents and intercepted communications, indicates the military may have been designing, testing, and stockpiling chlorine-based munitions to break military stalemates, specifically around Khartoum. While authorities in Port Sudan have denied these claims, asserting adherence to the Chemical Weapons Convention, international scrutiny has intensified. The United Nations Independent International Fact-Finding Mission for Sudan has confirmed it is investigating whether the manufacture of chlorine-based weapons constitutes a violation of international law. Additionally, former officials from the Organisation for the Prohibition of Chemical Weapons (OPCW) have urged a formal investigation. Their report cites digital evidence, witness testimony, and reports of acute respiratory distress in civilian areas between 2024 and 2025 as indicators of chemical weapon use. ## Timeline ### 2026-09-09: Sudan chemical weapons allegations prompt UN and OPCW scrutiny UN investigators and former OPCW officials are examining evidence of alleged chlorine-based chemical weapons use by the Sudanese Armed Forces during the ongoing civil war. 2 sources. https://clstr.news/cluster/sudan-chemical-weapons-allegations-prompt-un-and-opcw-scrutiny ### 2026-09-05: Sudan military accused of secret chemical weapons program Leaked documents and investigations by major US newspapers allege the Sudanese military has developed a secret chemical weapons program using chlorine munitions. 9 sources. https://clstr.news/cluster/sudan-military-allegedly-developed-chlorine-chemical-weapons --- Cite as: Sudan chemical weapons allegations.
