Dozens of journalists - many freelancers without news organisation backing - disappeared in 2012/13 in Syria. On Tuesday ISIS posted a video claiming to show kidnapped American journalist James Foley’s death. He was kidnapped in Syria nearly two years ago. The authenticity of the video, which was also posted on YouTube, could not be verified. YouTube later took down the 4 minute, 40-second video titled, ‘A Message to America,’ showing the journalist kneeling in a desert landscape, clad in an orange jumpsuit  - a reference to the uniforms worn by prisoners at Guantánamo Bay. Standing to his left is a masked ISIS fighter speaking in English with what sounds like an East London accent. Pulling out a knife, he says that Mr. Foley’s execution is in retaliation for the recent American airstrikes ordered by President Obama against the extremist group in Iraq.
