On December 2, 2021, the United Nations Investigative Team to Promote Accountability for Crimes Committed by Da’esh / Islamic State in Iraq and the Levant (UNITAD) presented its seventh report on ISIL’s activities in Iraq. According to a UN press release, UNITAD collected evidence on the executions carried out by ISIL at Badush Central Prison in 2014. UNITAD concluded that “crimes committed by ISIL members at Badush Central Prison constitute” crimes against humanity and war crimes.

UNITAD also focused on “the development and use of chemical and biological weapons by ISIL, and the financial mechanisms through which it sustained its campaign of violence.” UNITAD identified “more than 3,000 victims of chemical weapons attacks carried out by ISIL,” and revealed the details of the central ISIL treasury that is in charge of ISIL’s finances.
