U.S. Special Operations forces conducted a counterterrorism mission overnight in northwestern Syria that resulted in the death of Abu Ibrahim al-Hashimi al-Qurayshi, the leader of the Islamic State, President Biden announced Thursday.

Residents described an early-morning assault with helicopters and machine gun fire in the Idlib region, where first responders working in a part of Syria outside government control said they retrieved 13 dead bodies, including those of six children and four women. Biden said Qurayshi detonated a large explosion that killed members of his family and himself as the raid was underway.

The more-than-a-decade-long conflict in Syria, which erupted after a crackdown on protests against Syrian President Bashar al-Assad, has drawn in world powers, divided the country into a patchwork of territories, caused the deaths of thousands of people and created a refugee crisis of historic scope. Here’s what to know about Qurayshi, the U.S. military’s role in the country and the region where he was killed.
