British Police Evacuate 3 Subway Stations After Explosions

LONDON, July 21 - Just two weeks after a string of attacks on buses and subways in London that killed 56 people, the British police evacuated three subway stations in the city today after small explosions that sent commuters into a panic. But casualty numbers appeared to be low. The police said the Oval subway station in south London, Shepherd's Bush in the west and Warren Street in central London had been evacuated. There was also a small explosion on the No. 26 bus in the Hackney Road section that blew out the bus windows, police said.
