The man, named only as Saleh, said the masked militant who appears in several beheading videos was a senior figure in the extremist organisation responsible for murdering foreign captives. Jihadi John, who was recently unmasked as 26-year-old Londoner Mohammed Emwazi, was last seen in a video posted online which appeared to show Japanese hostage Kenji Goto lying dead. Saleh, who worked as a translator, also revealed that ISIS routinely subjected hostages to mock executions so that when their beheading did finally come they were not expecting to die. Speaking to told Sky News in broken English from Turkey after fleeing ISIS, Saleh said: 'When he killed Kenji Goto, I live showed this (saw this) but not near, from a little (distance). 'The big boss was there with them. Turkish man say "put this camera there, change place there" but John (was) the big boss. 'All time, all time say to all "fastly, fastly, fastly, we should finish". So respect him. Only he talks orders - others do.'
