Islamic State of Iraq and the Levant
Amnesty International has held ISIL responsible for the ethnic cleansing of ethnic and religious minority groups in northern Iraq on a "historic scale", putting entire communities "at risk of being wiped off the map of Iraq". In a special report released on 2 September 2014, the organization described how ISIL had "systematically targeted non-Arab and non-Sunni Muslim communities, killing or abducting hundreds, possibly thousands, of individuals and forcing more than 830,000 others to flee the areas it has captured since 10 June 2014". Among these people were Assyrian Christians, Turkmen Shia, Shabak Shia, Kaka'i, Yazidis and Sabean Mandeans, who have lived together for centuries in Nineveh province, large parts of which have come under ISIL's control.
