A senior ISIS leader who was involved in the killing of former U.S. Army Ranger Peter Kassig has been killed in a drone strike in Syria on Sunday, the U.S.-led coalition said.
Per an article by Fox News, coalition spokesperson Col. Sean Ryan said in a statement that the ISIS leader -- identified as Abu al Umarayn -- was killed in a precision drone attack along with several other members of the terror group in Syria's Badiyah Desert.
According to officials, Al Umarayn indicated that his group posed an imminent threat to Coalition Forces and he was involved in the killing of American Citizen and former U.S. Army Ranger, Peter Kassig, the report said.
"He has been linked to and directly involved with executing several other prisoners as a senior ISIS member."
Peter Kassig was 26 years of age and was an aid worker and a U.S. citizen. He was providing aid to Syrians who fled the country's civil war when ISIS captured him October 2013. According to his friends, he converted to Islam while in captivity and took the first name Abdul-Rahman.
In 2014, ISIS released a graphic footage that showed his brutal beheading. U.S. officials confirmed that the video was authentic.
