LONDON (AP) -- Terrorists tried to attack London eight times between the Sept. 11 attacks in the United States and last July 7, when suicide bombers killed dozens on the city's transport system, London's mayor said Monday. Ken Livingstone said there had been two attempted attacks since July 7, including a failed attack on the transport network on July 21. Livingstone did not provide details of the attempted attacks, but said those who threaten London comprise small groups of disaffected people who are fairly disorganized.
