Mohammed Emwazi was an ISIS recruit in Syria who beheaded captives on live videos in 2014 and 2015. Hostages nicknamed him ‘John’ because he was part of a quartet of terrorists who spoke English. They were dubbed ‘The Beatles’ and the media called Emwazi ‘Jihadi John’ after Liverpool legend John Lennon. He moved to the UK from Kuwait when he was six and graduated in IT and business from the University of Westminster.

Emwazi was seemingly instrumental in killings of western hostages such as aid workers and journalists, as well as 47 year-old Japanese video journalist Kenji Goto, who was beheaded on 31 January 2015.

Only five weeks later, on 10 March 2015, Sky News broadcast an interview with an ISIS defector who worked with Enwazi. Stuart Ramsay was the correspondent.

“He is the only person who has seen Jihadi John kill and admit to seeing it,” announced Ramsay on film. “His victim - Japanese journalist Kenji Goto… This man was there. He saw what happened.”

In a basement in Turkey on a pile of pillows set about by packets of Gauloise cigarettes, Ramsay talks with the gruff-voiced ‘defector’, who recounts life in ISIS in broken English. His speech needs subtitles and frequent confirmation on its meaning by Ramsay. The British journalist does not feed him exact quotes, but does lead the discussion. The ‘defector’ - known as Saleh - is wrapped in a red-patterned headscarf and speaks in his own voice about how ‘Jihadi John’ orchestrated killings.

“Syrian man, anyone can kill him,” says Saleh, “but foreigners, only John.”

‘Saleh’ was a translator who was also employed by the Turks to convince the hostages they would be safe, the report claims. The terrorists would change the names of the hostages to Muslim monikers to “convince the hostages they were amongst friends” adds Ramsay. The Japanese journalist Kinji was dubbed ‘Abu Saad’.

Ramsay concludes the report with the following: “Scared and emotional, Saleh ended the interview - he left knowing his life, like those of the hostages, is now in permanent danger from Islamic State.”

This is a curious ending as it seems to imply that ‘Saleh’ is now in ‘permanent danger’ due to the interview he just made with Sky News.

Like the reports from Russia and Romania, the correspondent does not say the defector is stating the truth, but instead reports on his “claims” that militants “routinely subjected foreign hostages to mock executions”.

But this, like the other reports above, has no independent verification.

On the comments section under the Sky News post on YouTube, the broadcast is mocked as fake, and the anonymous and masked structure of the set-up is so notoriously dubious, that it even has a reputation as “the famous Sky talking cloth”.

Internet chatter is obviously not proof.

So we talked to a Turkish journalist who also interviewed the same ‘Saleh’ and does not believe he is real.
