Britain's largest Sunni Muslim group has issued a religious edict condemning the London terrorist bombings calling it part of a perverted ideology.

The Sunni Council issued a fatwa Sunday, saying the July 7 attacks have no Islamic justification. The edict condemns all forms of terrorism and those who carry out such attacks.

Suicide bombers attacked three London subway trains and a double-decker bus, killing more than 50 people.

A British newspaper says Britain's domestic intelligence agency, MI-5, investigated one of the four suspected bombers last year, but determined he was not a threat and did not put him under surveillance. British officials had no comment.
