Hampshire Hostage In New IS Video
British hostage John Cantlie has appeared in a new video released by the so-called Islamic State.
The photographer from Winchester was captured in Syria in 2012 and was last seen on film in a video which emerged on 19 March.
In the latest video, he discusses the bombing of Mosul University, which happened a few days later.
He appears thin and has longer hair than in previous propaganda footage.
The Foreign Office said it was aware of the video and was ``analysing its contents''.
Mr Cantlie's skills as a journalist have been exploited by IS in an attempt to lend credibility to propaganda films, including a series titled Lend Me Your Ears.
His father Paul, 80, died from complications following pneumonia in 2014.
