The British photojournalist John Cantlie has appeared in another propaganda video produced by his captors Islamic State (IS).
While the videos have mainly featured Mr Cantlie alone, seated in an orange jumpsuit, the latest video is in the style of a documentary and shows him giving a tour of the Iraqi city Mosul, which IS, also known as ISIL or ISIS, overran last year.
He claims that "life in Mosul is business as usual" and that media reports suggesting the city is "depressed" and "living in fear" are "misleading".
IS captured Iraq's second largest city during its rapid advance across the north of the country in June 2014, when they murdered more than 2,000 Shiite prisoners and soldiers, according to Human Rights Watch.
The eight-minute video sees 43-year-old Mr Cantlie visit a market, a hospital and a police station purports to paint life in the bomb-hit city as stable.
A Foreign Office said it was "aware of the release of another video and are studying its contents".
In the video, Mr Cantlie tells the camera: "The media likes to paint a picture of life in the Islamic State as depressed, people walking around as subjugated citizens in chains, beaten down by strict, totalitarian rule.
"But really apart from some rather chilly but very sunny December weather, life here in Mosul is business as usual."
The hostage has been held captive for more than two years by IS militants. In previous instalments he has delivered his message from behind a desk and wearing an orange jumpsuit.
Other footage released by the group in October purported to show Mr Cantlie in the embattled Syrian city of Kobani, as a battle raged to take the strategically-important town.
The last video of Mr Cantlie released in November saw him give an account of what he claims was a failed rescue attempt by American forces in July.
In it Mr Cantlie says he accepted "long ago" that his fate is "overwhelmingly likely" to be the same as other captives.
British aid workers Alan Henning and David Haines and American journalists James Foley and Steven Sotloff were beheaded on camera by the jihadi organisation.
Mr Cantlie's father Paul, 80, died from complications following pneumonia last year shortly after releasing a video from his hospital bed pleading for his son's release.
His sister, Jessica Cantlie, has previously appealed for "direct contact" with those holding him.
