ITV News exclusive: The extremists in Jihadi John's British terror cell

The family of Alexe Kotey, who is alleged to be a member of the Islamic State (IS) terror cell dubbed "The Beatles" have said they are "are deeply distressed" at the claims and confirmed they have not seen him "for a number of years".

London mayoral candidate George Galloway has claimed he has no memory of meeting an IS recruiter thought to have campaigned alongside him for a pro-Palestinian group.

Alexe Kotey is believed to have travelled to Gaza in February 2009 on an aid convoy organised by the 'Viva Palestina' group, led by the former MP.

The campaign group claimed the convoy took more than £1 million in aid to the region, including ambulances, medicine and food.

Mr Galloway today told ITV News he does not remember meeting Kotey.

A spokesman said: "There were 500 people on that convoy and George can't ever remember laying eyes on this guy. It's possible he was there but George doesn't remember meeting him."

A British man identified as an associate of Islamic State militant "Jihadi John", was a key recruiter for the terror group, an anti-terror source has told ITV News.

Alexe Kotey is said to have played a hand in radicalising a string of fellow London men to join the extremist terror group.

Among them was Hamza Parvez, known as Abu Hamza al-Britani, whom ITV News previously revealed left his London home to join Isis.

Kotey also played a role in radicalising brothers Fatlam and Flamur Shakalu.

Fatlam, 20, known as Abu Musa al-Britani, became a suicide bomber who blew himself up last May in Ramadi. Flamur, 23, was also killed fighting in March.

Also part of Kotey's circle of associates were London fighters Mohammed Nasser, killed by shrapnel while fighting for Isis in 2014, and engineering student Mohammed el-Araj, 23, who died in Syria the previous year.

A west London mosque attended by Mohammed Emwazi, dubbed Jihadi John, and two members of his British terror cell has condemned their actions.

Islamic State militants Aine Davis and Alexe Kotey, named exclusively by ITV News, attended London’s Al-Manaar mosque with Emwazi, where they were marginalised for extremist views.

In a statement, the director of the mosque Saleha Islam stressed that she was "fully committed to ensuring that our children are not groomed and radicalised".

In a statement on their website, the mosque added: "Mosques are not like Churches that cater for parishioners, instead it is a place for worship where people come to pray, what sort of ideas they have in their minds is something that we do not know of and we cannot control.

"Prophet Mohammed always taught us to be on the middle path and those who join ISIS and the like have no understanding of the faith and we do not support their ideology or actions."

As ITV News reveals the identity of two British associates of ISIS executioner 'Jihadi John', a community worker has said one of the men Alexe Kotey, was part of a group that used to hold classes at a mosque.

Speaking anonymously, they described Kotey as "certainly the most vocal".

"He would definitely be standing there with, I’d say, a dozen boys all listening to him. He was the speaker. He was the spokesman in that little group", they said.
