British police investigating the botched London subway attack of July 21 said Thursday they had charged two sisters for failing to disclose information under anti-terror laws. The city's nerves were further rattled by a message from al-Qaeda warning of more bloodshed, but people made efforts to carry on.

In a show of force, officers armed with submachine guns patrolled uncrowded subway stations and police helicopters hovered over city streets as one of the busiest Underg-round lines reopened Thursday four weeks to the day after suicide bombers killed 52 people.

Undercover officers mixed with a lighter-than-usual load of subway commuters many Londoners no doubt mindful that terrorists had attempted similar attacks exactly two weeks after the deadly July 7 transit bombings.

"People didn't seem frightened or apprehensive, they were just reading their newspapers and getting on with things, just as the English do," said commuter Pat Wish.
