Islamic State releases video it says shows British journalist John Cantlie

BEIRUT (Reuters) - Islamic State militants fighting in Iraq and Syria released a video on Thursday that they said shows British journalist John Cantlie in captivity saying he will soon reveal "facts" about the group to counter its portrayal in Western media.

The Islamic State, which controls territory in Syria and Iraq, has already beheaded two American journalists and one British aid worker in recent weeks in what it said was reprisal for U.S. air strikes against it in Iraq.
