It’s been a while, but here’s a November report from the UN Investigative Team to Promote Accountability for Crimes Committed by Da’esh/Islamic State in Iraq and the Levant. It contains new information about ISIL’s “development and use of chemical and biological weapons.”
Chemical weapons:
Evidence suggests that ISIL manufactured and produced chemical rockets and mortars, chemical ammunition for rocket-propelled grenades, chemical warheads and improvised explosive devices. Furthermore, the ISIL programme involved the development, testing, weaponization and deployment of a range of agents, including aluminium phosphide, chlorine, clostridium botulinum, cyanide, nicotine, ricin and thallium sulphate.
