British hostage John Cantlie has appeared in a new video released by the Islamic State terror group.
The photographer was captured in Syria in 2012 and was last seen on film in a video which emerged on March 19.
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.
