A British terror fanatic married into a top ISIS family and played down his role after being captured, according to a Brit who fought the terror group.
Jack Letts, 24, dubbed Jihadi Jack, from Oxford, reportedly wed the daughter of a tribal leader in Iraq, who would have become an Emir after pledging allegiance to ISIS, it is said.
Alan Duncan, who fought alongside the Kurds in the battle against ISIS, said sources in Iraq and Syria told him Letts has a son with the woman.
The former British soldier said his marriage into a high-profile ISIS family reflected his senior rank in the terror group.
He told The Sun: "He definitely married into a top ISIS Iraqi family. Jack is clearly higher within ISIS than he has admitted to.
“You don't marry into a family like that and get a wife like that if you're nothing.
“The tribal leaders are what you would call Imans - as soon as a tribal leader gives his allegiance to ISIS he becomes an Emir. They basically become a leader in ISIS."

Letts previously insisted he did not think British citizenship “was a big deal” after his passport was revoked.
Speaking from a jail cell in Syria, he said he was “not surprised” at the UK Government’s decision.
A dual UK-Canadian national, Letts, 24, left Britain in 2014 at age 18 to join IS.

He said: “I don’t think British citizenship is a big deal. It’s not something I recognise. I don’t think where you are from is based on a piece of paper.”
The Muslim convert has been in a Kurdish-run jail in Syria since he was captured trying to flee Turkey in 2017.
Lett’s parents, John Letts, 58, and Sally Lane, 57, called the UK Government cowardly.
John said: “I thought we had the right to be innocent until proven guilty.”
Letts says he “never killed anyone” and has made a “stupid mistake”.
Earlier this year, his parents John Letts and Sally Lane were convicted of funding terrorism by sending their son money.
The couple were spared jail after sending him £223 and attempting to wire another £1,500.
