A 27-year-old student from London who fled Britain to join the Islamic State (ISIS) terrorist group in Syria in 2014 has become the first known ISIS recruit from the UK to die in the custody of the Syrian Democratic Forces (SDF).
Ishak Mostefaoui, an Algerian origin student at the University of Westminster, was killed while attempting to escape SDF custody recently, according to a BBC report.
It is believed the death occurred during serious disorder in a jail in Hassakeh, which houses ISIS prisoners from various countries. The BBC said that the death and surrounding circumstances have not been officially confirmed.
After being captured last year, Mostefaoui was held in a prison in north-east Syria - a former school converted into a prison - controlled by the Kurdish-led, US-backed Syrian Democratic Forces.
Sources told the British broadcaster that he was one of around 10 British men and 30 British women being held by the militia, but he was the first to die in SDF custody.
