As in the hunt for the ISIS fighter dubbed “Jihadi John,” U.S. officials are conducting detailed analysis of the clues on the video. In the “Jihadi John” videos, believed to have been shot in Syria, authorities say they have been able to identify that masked figure with a British accent who appeared to murder Western journalists and aid workers. He is believed to be a British citizen, officials say, though he has not been publicly named.
The potential role of an American ISIS recruit – which would not be a first for the terror group — comes as the White House today began a three-day effort with community leaders to stem the flow of the terror pipeline from the U.S. to the Middle East.
One front on which ISIS has been successful in recruitment, analysts and U.S. officials have said, is on social media. J.M. Berger, terrorism expert and author of a forthcoming book on ISIS, estimates that the group has 30,000 to 40,000 supporters active online every day.
