The head of United States Central Command says Islamic State leader Abu Bakr al-Baghdadi was buried at sea after a weekend raid on his compound.

Gen. Frank McKenzie told reporters Wednesday that al-Baghdadi died after he exploded a suicide vest just before U.S. troops were going to capture him.

McKenzie says two children were killed in the explosion set off by the Islamic State leader.

The U.S. said earlier that three children were killed.

U.S. forces raided the compound in northwestern Syria on Saturday. There were no U.S. casualties.
