An online video released Saturday night purported to show an Islamic State of Iraq and Greater Syria (ISIS) militant behead Japanese journalist Kenji Goto, ending days of negotiations by diplomats to save the man. The video, released on militant websites and highlighted by militant sympathizers on social media sites, bore the symbol of ISIS’s al-Furqan media arm. Though the video could not be immediately independently verified by The Associated Press, it conformed to other beheading videos released by the extremists, who now control a third of both Syria and neighboring Iraq in its self-declared caliphate. The video, called “A Message to the Government of Japan,” featured a militant who looked and sounded like a militant with a British accent who has taken part in other beheading videos by ISIS.
