There has been no official confirmation of reports that Abu Bakr al-Baghdadi was killed in the raid. He has been wrongly reported dead on several previous occasions.

He said helicopters had launched an assault that lasted 30 minutes, firing missiles at two houses and flattening one, before troops became active on the ground.
