U.S. Cautioned U.K. About London Bomb Suspect

The Federal Bureau of Investigation warned British authorities that Mohammed Sidique Khan, one of the London bombers, had affiliations with terror groups just before the July 7 bombings, the Associate Press (AP) reports.

A terror informant who was arrested in the U.S. in 2004 identified Khan as a threat, but U.S. officials say their warning was too vague to stop the attack, the AP reports.

The informant, identified as Mohammed Junaid Babar, told the U.S. that Khan was a potential terrorist, but he offered no specific information on the London bombings.

Khan and Shehzad Tanweer, another bomber, were under surveillance briefly in 2004 by Britain’s Ml5 security agency, but it was found that he posed no immediate threat.

British officials refused to comment on the subject.
