Fighters with the armed group calling itself “Islamic State” (IS) have systematically targeted members of non-Arab and non-Sunni Muslim communities. Despite worldwide condemnation, the IS has shown no intention of putting an end to the war crimes and crimes against humanity which its fighters have been committing on a large scale, including against the Iraqi women and girls they have abducted and continue to hold captive. Any party, in Iraq or outside, with any influence over the IS should use that influence to secure the release of these captives.
