(BBC) Jack Letts, who left the UK to join the Islamic State group as a teenager, has said he had been an “enemy of Britain.”
The Muslim convert, who is in custody in a Kurdish jail, admitted he was once ready to carry out a suicide attack.
The BBC interviewed the 23-year-old in October but it can only be reported now after his parents were convicted of funding terrorism by sending him cash.
The Home Office did not comment but has previously said it would try to block IS recruits hoping to return to the UK.
The interview is the fullest account yet of the Briton’s time with IS in Syria, and Jack Letts said he was not speaking under duress.
