|British War Criminals of ISIS|
A British jihadist who has boasted about the execution of prisoners while fighting in Syria could face war crime charges if he returns to the UK, it has emerged.
Former Cardiff student Reyaad Khan, 20, was one of three young Britons who appeared in a recruitment video for the terror group Islamic State (IS) in June.
He has since bragged on Twitter about seeing prisoners killed and alluding to being involved. He also appears to suggest he has a stepbrother who is now fighting in Syria.
Geoffrey Robertson QC, a former UN appeals judge, said if the claims were proven then the fanatic could be prosecuted for war crimes in the UK.
Khan is said to use the Twitter alias Abu Dujana RK, who posted alleged images of corpses last month adding: “Guys we caught and executed. This is how they looked less than an hr l8er.”
In another posting, Abu Dujana wrote: “Executed many prisoners yesterday.” That Tweet prompted another IS fighter, from Portsmouth, to reply: “Epic executions bro, we need to step it up like the brothers in Iraq.”
Mr Robertson said: “Boasts on social media are admissible evidence for the prosecution. If you fight for Isis your complicity in war crimes and crimes against humanity would be virtually inevitable.
“Anyone thinking of joining combat groups in Syria should be made aware that war crimes can be tried and punished at the Old Bailey and so can murders committed abroad.”
