Pentagon claimed to have killed a high level Islamic State commander Abu Wahib in a US-led coalition airstrike.
Abu Wahib, also known as the Desert Lion, had appeared in execution videos.
An air raid launched by a US-led coalition killed a senior IS official and three others in a vehicle near the Iraqi town of Rutba last week, a Pentagon spokesman Peter Cook said.
He added the death of Abu Wahib, given his senior role in military planning in Iraq’s Anbar province will impede terror group’s ability to conduct operations.
“ISIL leadership has been hit hard by coalition efforts and this is another example of that,” Cook told reporters, using an alternative acronym for the group. “It is dangerous to be an ISIL leader in Iraq and Syria these days, and for good reason.”
