(HRW) – The “unimaginable horrors” that the Islamic State (ISIS) is committing against the minority Yezidis, documented in a report released on June 16 by the UN-mandated Independent International Commission of Inquiry (COI) on the Syrian Arab Republic, shows the urgent need for concrete steps to ensure justice for these crimes. In August 2014, ISIS fighters overran Yezidi towns and villages around Sinjar, in northwestern Iraq, executing many men and capturing women and girls. Their intent soon became clear in slave markets ISIS set up in Mosul and elsewhere, where they sold the women and girls to their fighters into sexual or domestic slavery.
