A second video has been released by Isis featuring British photojournalist John Cantlie.
Video experts believe Mr Cantlie is being held under severe duress by Isis (who call themselves the Islamic State) and may have been forced to read from a script. These are not the images we should associate with Mr Cantlie.
A freelance British photojournalist, he has written and recorded videos for the Sunday Times, the Sun and the Telegraph as well as taking scores of photographs which give us an insight into life in Afghanistan and Syria...
Syrian opposition fighters pass an old man as they patrol the northern city of Aleppo in November, 2012.
Cantlie was kidnapped in July 2012, alongside fellow freelance photojournalist Jeroen Oerlemans.
The Independent's Kim Sengupta, who had been in the region around the same time, said that the jihadist groups were in a minority at that time and the rebels in Syria were grateful that journalists were there to report on the atrocities of the regime.
I met Cantlie again in London, in September 2012. He was going back to Syria and wanted to meet the fighters I knew who had said they’d helped to free him.
I, too, was supposed to be returning to Aleppo and there were vague plans to meet up. But I was diverted, and in November, while I was in Gaza for the Israeli offensive, I heard that John had been kidnapped again and, with him, Jim Foley.
