A leader of ISIS's branch in Libya was struck and presumed killed by a U.S. airstrike Friday night, a defense official told NBC News.
The terror suspect was struck by a missile fired by an F-15 fighter/bomber. The official said the operation began before the Paris attacks and was not related to that event.
Kevin Baron, editor of Defense One and a national security analyst for NBC News, said the man goes by the nom de guerre Abu Nabil.
