(HRW) – The extremist group Islamic State (also known as ISIS) has carried out systematic rape and other sexual violence against Yezidi women and girls in northern Iraq. Human Rights Watch conducted research in the town of Dohuk in January and February 2015, including interviewing 20 women and girls who escaped from ISIS, and reviewing ISIS statements about the subject. Human Rights Watch documented a system of organized rape and sexual assault, sexual slavery, and forced marriage by ISIS forces. Such acts are war crimes and may be crimes against humanity. Many of the women and girls remain missing, but the survivors now in Iraqi Kurdistan need psychosocial support and other assistance.
