By More Explosions
* It happened again in London yesterday.
As many as four midday explosions rocked the English capital, a chilling replay of the four suicide blasts that killed 56 people there exactly two weeks earlier.
Yesterday's explosions were much less destructive. No one was injured, but the eerie similarity to the July 7 blasts unnerved many Londoners.
Again, the targets were three subway trains and one of the city's famous red double-decker buses.
But the explosive devices appeared to be smaller than those used two weeks ago, police said, and not all of them went off.
A subway rider at the Warren Street station claimed he saw a backpack explode. "He said that a man was carrying a rucksack and the rucksack suddenly exploded. It was a minor explosion," said Ivan McCracken, who also was in the station. "The man then made an exclamation as if something had gone wrong. At that point, everyone rushed" from the car.
News reports said police were looking for a man in a blue shirt with wires sticking out of it.
Three subway lines were temporarily shut down after the blasts. The bus had its uppermost windows blown out.
