More than five years after the Islamic State first took root in Iraq and Syria, President Trump confirmed on Sunday its leader, Abu Bakr al-Baghdadi, was killed in Syria during a raid by U.S. special operations forces.

Baghdadi detonated a suicide vest after U.S. forces chased him into a dead-end tunnel, killing himself and three of his children he was using as human shields. The explosion largely destroyed Baghdadi’s corpse, but DNA tests taken at the site of the raid confirmed his identity, according to Trump.
