Residents stand among debris after a car bomb detonated in Baghdad on July 19, 2014, one of a series of such attacks on that day. Abu Abdullah describes one of the bombers from that day, a German man: "He was in Baghdad for the first time in his life, and 45 minutes later he was dead. I thought: Now even people from Germany are coming here in order to blow themselves up."
