The FBI is asking for help identifying a masked man in an ISIS execution video.
FOX News Radio's Rachel Sutherland reports from Washington.
The Jihadist -- who may be an American -- is seen in a recent ISIS recruitment video dressed in military fatigues with the black ISIS flag behind him. He speaks with a North American accent, as he refers to men digging ditches.
(Jihadist in ISIS recruitment video) "We're here with the soldiers of Bashar. You can see them now digging their own graves in the very place where they were stationed."
The FBI's request for help is part of a greater effort to identify and stop Americans fighting for ISIS. Counter-terrorism officials say at least a dozen U.S. citizens have gone overseas to join the terrorist group.
