On Nov. 30, the Islamic State (ISIS) announced that its leader, Abu al-Hassan al-Hashimi al-Qurayshi, had been killed in battle and that his successor, Abu al-Hussein al-Husseini al-Qurayshi, was now in place. Hours later, the United States military’s Central Command confirmed the death of Abu al-Hassan, adding that it had occurred in Daraa, in southern Syria, in mid-October at the hands of “the Free Syrian Army” (FSA). For its part, the U.S. partner force in Syria, the Syrian Democratic Forces (SDF), denied any role in the ISIS leader’s death — suggesting this may have been the first such leadership death not caused by U.S. action.
