The fog of war is lifting. A new U.N. report reveals ISIS executed 741 civilians, including children, during the nine-month battle for Mosul that ended in July. The militants also reportedly used civilians as human shields and unwilling suicide bombers. Another 461 were killed by Iraqi and U.S.-led airstrikes, taking the civilian death toll over 2,500. The “shocking human rights abuses” in the report could aid future war crime prosecutions. Meanwhile, the Syrian army says it’s retaken Deir al-Zour, ISIS’ last major stronghold in Syria.
