Three teenage boys from Coventry have been lured to Syria to fight for Isis, their families have told BBC Newsnight.
The boys did not tell their parents they were leaving, and one father said his son was brainwashed by the local Imam.
The Imam denies this.
The boys are believed to be among the 500 Britons who have left the UK to join the conflict in Syria.
