A BOURNEMOUTH MP says the final two suspected members of an Islamic State execution group dubbed 'The Beatles' should be tried at The Hague.

Defence minister Tobias Ellwood, who also represents Bournemouth East, spoke to a national newspaper after Britons Alexanda Kotey and El Shafee Elsheikh were captured in Syria.

Both are under guard in the caliphate's former heartland, having fallen into the hands of Kurdish militia fighters in January.

It remains unclear who will determine the pair's fate, with a US Department of Defence spokesman saying they were "still considering options".

The Home Office refused to comment on reports that both men had been stripped of their British citizenship, but Defence Secretary Gavin Williamson told The Sun he did not want to see the pair prosecuted in the UK.

Mr Ellwood called for their trial to be held at an international war crimes court.

He told the Daily Telegraph: "Given the scale of foreign fighters we should consider an agreed international process involving The Hague, which ensures terrorists from any origin are transparently and fairly held account for their actions."

The MP lost his brother in a terrorist attack in Bali in 2002. Last year, he tried to save PC Keith Palmer, who died during the attack in Westminster.

"Guantanamo Bay created a new combatant status that bypassed the Geneva convention, used torture and failed to address a wider global jihadist insurgency that continues today," he said.

"The horror of 9/11 meant we briefly lost sight of the standards and rule of law that took centuries to develop and fundamentally distinguish us from the terrorist."

Kotey allegedly tried to smuggle himself into Turkey to escape capture.

Along with Mohammed Emwazi - the killer nicknamed Jihadi John - and Aine Davis, they are thought to have been part of a group named after the '60s band because of their English accents.

The four Londoners were linked to a string of hostage murders in Iraq and Syria during the bloody Islamist uprising and gained global notoriety.

US officials said Kotey and Elsheikh "are suspected to have participated in the detention, exploitation and execution of Western detainees".
