UK jihadists prisoner swap reports 'credible' - Whitehall

Reports that UK jihadists were involved in a prisoner swap between Islamic State (IS) and Turkey are "credible", Whitehall officials have told the BBC.

It has been reported that Hisham Folkard, 26, and Shabazz Suleman, 18, were among as many as 180 IS fighters traded for 46 Turkish hostages.

The Turks were taken prisoner from their country's consulate in Mosul, Iraq, in June and released last month.
