Isis fighters
Research reveals the web habits of Islamic State fighters revolve around pornographyZaid Al Fares

London Mayor Boris Johnson branded Britons fighting for Isis as "literally w***ers", after research revealed their web habits included watching online porn.

Research by MI5 found jihadists watch vast quantities of pornography online, making a mockery of Islamic State's (IS) religious propaganda.

Videos released by the terror group has shown public whippings of people accused of watching erotic material online.

Johnson said IS fighters were "tortured losers" who were incapable of normal relationships with women.

He called for the terrorist group to be "demystified" and exposed.

Speaking to The Sun, Johnson said: "If you look at all the psychological profiling about bombers, they typically will look at porn. They are literally w***ers. Severe onanists.

"They are tortured. They will be very badly adjusted in their relations with women, and that is a symptom of their feeling of being failures and that the world is against them.

"They are not making it with girls, and so they turn to other forms of spiritual comfort — which of course is no comfort."

Johnson, who is standing for parliament in May's general election for the Conservative party, also claimed Muslim leaders were "not explaining" properly why members of the communities succumbed to the lure of violence and bloodshed.

He said: "I often hear voices from the Muslim intelligentsia who are very quick to accuse people of Islamaphobia.

"But they are not explaining how it can be that this one religion seems to be leading people astray in so many cases. They are not being persuasive in the right way with these people."
