A 21-year-old man from Oxford has been charged with being a member of Isis, according to officials from the Kurdish region of Syria.

Officials told the BBC Jack Letts - known around the world as "Jihadi Jack" - has been charged after being captured by the Kurdish YPG (People's Protection Units) in May.

Their statement said Letts had been taken to a prison in Qamishli, Rojava, in northern Syria. This is the first time Kurdish forces have confirmed his capture as a prisoner of war.

Letts converted to Islam while at Cherwell comprehensive school in Oxford. He first travelled to the Middle East in 2014, aged 18, after dropping out of A-level study. He ventured to Syria via Jordan.

Although he has previously denied any connection to Isis, he remains under investigation by global anti-terror units.

His parents, John Letts and Sally Lane, were convicted for funding terrorism charges earlier this year after sending him around £1,700. They have appealed this decision and are expected to appear at the Supreme Court soon.

They claim their son is not fighting for Isis but is acting as a "humanitarian" in the Middle East. They have criticised the Government for "[leaving him] in a hole with no trial, no process, no charge".

A spokesman for the Foreign Office said: "As all UK consular services are suspended in Syria, it is extremely difficult to confirm the whereabouts and status of British nationals there.

"Anyone who does travel to Syria, for whatever reason, is putting themselves in considerable danger."
