Two Britons who went to Syria to fight IS have told of their battles on the front line - and how they vowed to kill each other rather than get captured.
Jamie Read and James Hughes told how they dodged bullets during chaotic patrols with Kurdish forces after recording a "goodbye" video for their families in case they died.
They described spending hours lying in the "pitch black" in no-man's land, in conditions they said were reminiscent of World War One.
On one occasion, it was so cold that a young Kurdish comrade collapsed with hypothermia - "body-popping" on the ground next to them.

In an exclusive Sky News interview after their return to the UK, the pair also revealed how panic alarms have been installed in their homes, amid fears they could be targets for IS supporters.
They strongly denied being mercenaries, telling how they had sold possessions to fund their flights and had returned to the UK to "mounting debts and bills".
They had not been paid "a penny" for their exploits, though they had been "treated like royalty" by some of the Kurdish troops, the men said.
And the former soldiers gave a detailed account of their time in Iraq and Syria, explaining that they had travelled to fight IS militants because they had "zero tolerance for terrorism".
Describing what had prompted them to travel, Mr Read said the beheading of British aid convoy volunteer Alan Henning had been the final straw.
