The Archbishop of York has condemned Muslim extremists as no more than criminals
Dr John Sentamu said religion, poverty or prejudice were no excuse for killing.
"It doesn't matter what god you worship - if your god is sending you to maim and kill people, I say to myself, 'what kind of a god is that?'" he said.
Dr Sentamu added: "I am quite sure some people feel alienated from main, successful Britain, but again I would like to say alienated people do not necessarily resort to acts of violence."
The tough line from Dr Sentamu - number two in the Church of England hierarchy - amounted to a ringing rejection of the arguments that terrorism is inspired by "Islamophobia" or by British military intervention in Iraq and Afghanistan.
It added to a series of criticisms he has made in recent months of multiculturalism, the Left-wing doctrine which encourages different ethnic groups to develop separate interests, and his calls for more respect for British history and traditions.
