The Islamic State in Iraq and Syria posted a video on Tuesday that it said showed the beheading of James Foley, an American journalist who was kidnapped in Syria nearly two years ago, according to a transcript released by the SITE Intelligence Group.
The authenticity of the video, which was also posted on YouTube, could not be verified, and a telephone call placed to Mr. Foley’s family was not immediately returned. YouTube later took down the four-minute, 40-second video.
