(Al-Monitor)- The world has borne witness to countless crimes committed by Islamic State militants in Iraq and Syria over the past year. Iraqi and Syrian children have not been spared from these atrocities. Several reports by international human rights organizations have documented IS’ use of children for suicide operations, executing prisoners, guerrilla warfare and also as human shields.While IS, as the main Sunni militant group in Iraq, is brainwashing children and young people to fight Shiites, largely Shiite forces such as the Iraqi Popular Mobilization Units are reportedly also training child soldiers to fight Sunni extremists, including IS.
