A US-led coalition air strike has killed a senior "Islamic State" (ISIS) leader in Iraq's Anbar province and three other jihadists, the Pentagon said Monday, according to AFP.

"On May 6, a coalition air strike targeted Abu Wahib, ISIL's military emir for Anbar province and a former member of Al-Qaeda in Iraq who has appeared in ISIL execution videos," Pentagon press secretary Peter Cook said, using an acronym for the ISIS group.
