“U.N. investigators are compiling evidence on the development and use of chemical weapons by Islamic State extremists in Iraq after they seized about a third of the country in 2014, and are advancing work on the militant group’s gender-based violence and crimes against children, Sunni and Shiite Muslims, Christians and Yazidis, the head of the investigative team said Wednesday. Christian Ritscher told the U.N. Security Council that survivors of a March 2016 chemical attack against Taza Khurmatu, a mainly Shia Turkmen town south of Kirkuk in northeast Iraq, were still deeply impacted when he visited earlier this year. He said he has prioritized the investigation of chemical weapons used by the Islamic State, also known as ISIL. ‘ISIL weaponized several chemical agents and deployed these as chemical rockets and mortars, as well as improvised explosive devices, in the vicinity of Taza Khurmatu’ which hit residential neighborhoods and agricultural fields, Ritscher said.”
