LONDON (AFP) - There is no evidence to suggest that suicide bombers were behind the series of deadly blasts in London, the city's police chief told reporters.
"There is absolutely nothing to suggest that this was a suicide bombing attack although nothing at this stage can be ruled out," Metropolitan Police Commissioner Ian Blair said of the attacks on three underground trains.
An anti-terrorism official, Andy Hayman, added that in the train bombings, "each device that was used had less than 10 pounds (4.5 kilogrammes) of high explosive" and their placement was "likely to be on the floor of the carriage."
Blair said that in the case of the double-decker bus blown up there was also no indication that a bomber deliberately set off an explosive device while on board the vehicle.
