BAGHDAD (Reuters) - Islamic State insurgents who control territory in Iraq and Syria released a video on Tuesday purportedly showing the beheading of U.S. journalist James Foley, who had gone missing in Syria nearly two years ago.

The video, titled "A Message To America," was posted on social media sites. It was not immediately possible to verify.
