The ISIS execution gang fronted by 'Jihadi John' contained two other British extremists who learned radical Islam together in London, ITV News can reveal.
Until now the identities of Emwazi's masked associates have not been known - but they can now be named as Londoners Alexe Kotey and Aine Davis.
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."
During a nine month investigation by ITV News, we learned of Kotey’s role influencing extremists in west London.
After ITV News named them as members of an IS terror cell dubbed "the Beatles", here's what we know about Alexe Kotey and Aine Davis.
