Police in London have arrested two men in connection with four attacks on three subway trains and a double-decker bus on Thursday, a scene hauntingly similar to deadly explosions set off by four suicide bombers exactly two weeks before. It was an inescapable message that life in London now means living with the threat of terror.
The explosive devices were either faulty or too small to cause bloodshed, and the only reported injury turned out to be an asthma attack. But the lunch-hour blasts rattled a capital already on edge after the July 7 explosions, which killed 52 people and four suicide bombers.
Police said one man was detained near Downing Street, site of the prime minister's residence; the other was picked up near Tottenham Court Road, close to the Warren Street subway station where one attack took place.
"We can't minimize incidents such as this," Prime Minister Tony Blair said. "They're done to scare people, to frighten them and make them worried."
They did that.
Authorities said it was too early to determine whether the attacks were carried out by the same organization as the July 7 blasts _ or whether they were linked to al-Qaida.
