John Cantlie, British journalist captured by Isis, appears in first video for more than a year

John Cantlie, the British photojournalist kidnapped by Islamic State (Isis) in 2012, has appeared in a new propaganda video for the group for the first time in more than a year. In the video, a gaunt-looking Cantlie claims to be in the Isis-held city of Mosul, where he is seen criticising American airstrikes on IS (Daesh) media kiosks, in the shadow of a bombed-out building.

Cantlie has made regular appearances in videos on behalf of IS since his capture, appearing in Mosul, Aleppo and the Syrian town of Kobani. Security services believe he is making the videos under duress.

The new clip sees Cantlie fronting a documentary style clip in English, in which he mocks the expense the US has gone to in order to level a small metal kiosk used, he claims, to hand out pamphlets. He says: "what's really amazing, given the amount of money that America is spending on this war, is that it would go to the effort of destroying a small shack like this, in the middle of Mosul".

He is also filmed near a bombed-out house, saying that "such attacks prove the failed strategy of the American bombing campaign".

Cantlie had previously appeared in a series of propaganda videos on behalf of IS, entitled Lend Me Your Ears, in which he hits out at the US campaign against the Islamist terror group. He produced seven videos in the series, initially from within his IS prison in an orange jumpsuit, but later on location in territory controlled by the group. Previous videos have been longer and had higher production values than the current one, which ends abruptly, leading analysts to suggest it is part of a longer piece.

Cantlie was captured by IS for a second time in November 2012, alongside American journalist James Foley. He has worked for several newspapers, including The Sunday Times, The Sun and The Sunday Telegraph. IS beheaded Foley in August 2014.
