The United States believes it has identified the masked militant thought to have beheaded two American journalists, FBI Director James Comey told reporters on Thursday.
NPR’s Brian Naylor reports that Comey declined to identify the man. The videos, released by the Sunni militant group Islamic State, show a masked man speaking English in a British accent. The video then shows the man beginning to cut the heads of the Americans.
The AP reports that Comey did not comment on whether the U.S. believes the man in the video also conducted the beheadings.
The AP adds that Comey said that about 100 Americans “have either tried to go to Syria and been arrested, gone successfully, or gone and come back. But he isn’t breaking down the numbers any further.”
