2nd Wave of London Attacks

LONDON (AP) - British police now say no one was hurt in today's attacks on London subways and a bus. Officials say one person suffered an asthma attack during the coordinated lunch-hour blasts.

London's police chief says, "Clearly , the intention must have been to kill" with the small explosions that hit the Underground and a bus.

Ian Blair won't say if anyone has been arrested in the attacks. But he says evidence collected from the crime scenes could help investigators.

A security and defense expert says an official close to the
investigation told him it appeared that two devices detonated, but
the other two didn't.

A spokesman for London Transport says it wouldn't be realistic to check bags or install scanning machines in a subway system that carries three (m) million people a day, and a bus system double that size.
