A baby-faced British ISIS recruit from Coventry has become the first person to be executed by the terror group as a spy.

Mohammed Ismail, who was nicknamed Osama bin Bieber, after the Canadian pop star because of his youthful appearance, fled the UK to join the terror cult when he was 18-years-old.

But Ismail, who was reported missing by his parents in March 2014, is thought to have been killed after giving away the movements of Nasser Muthana, a noted ISIS propagandist.

Muthana, an aspiring doctor from Cardiff, was killed by a drone strike in Mosul in 2016.

He travelled to Syria five months earlier and appeared in an ISIS recruitment video with Reyaad Khan, another Cardiff resident.

Nasser had taken £100 from his father to go on an Islamic seminar in Shrewsbury in November, but instead went to Syria.

Three months later his brother Aseel, 17, left the house saying he was going to a friend’s for the night, but the following evening it transpired that Aseel had obtained a second passport by lying about his age and was in Cyprus, travelling to Syria.

Khan is thought to have been killed by an RAF drone strike in August 2015, it is not clear where Aseel is at present.

According to one account, Ismail was killed in Raqqa, and the execution was filmed.
