US-Led Airstrike Kills ISIS Leader Responsible for Death of American Aid Worker

A senior ISIS leader, responsible for the death of American aid worker Peter Kassig, was killed in a U.S.-led airstrike in Syria.

NBC News said the Pentagon has confirmed that Abu al-Umarayn was killed, along with other Islamic State members in the desert of southwest Syria on Sunday.

"Coalition forces conducted precision strikes against a senior ISIS member, and killed Abu al Umarayn, and several other ISIS members on Dec. 2 in the Badiyah Desert, Syria," the Pentagon said in a prepared statement on Monday.

"Al Umarayn had given indications of posing an imminent threat to Coalition Forces and he was involved in the killing of American Citizen and former U.S. Army Ranger, Peter Kassig.”

Kassig, 26, of Indianapolis, was taken prisoner in 2013 while delivering humanitarian aid in Syria. A video released in 2014 showed a man with a British accent standing over a severed head. The man said it was Kassig’s.

The U.S.-led coalition has killed top ISIS officials in Syria and Iraq over the last several years.
