Police in London have warned people to remain cautious following the bomb attacks during Thursday morning¿s rush hour on the city's transport system. The attacks are believed to have killed at least fifty people and injured around seven hundred more.
This report from Sanjay Dasgupta.
Speaking on television just hours after the attacks, the British Prime Minister, Tony Blair, promised an intense investigation by the police and security services to track down those responsible. Mr Blair also said he knew those behind the attacks had acted in the name of Islam but he stressed that the overwhelming majority of Muslims abhorred the bombings as much as he did.
The first attack came just before nine in the morning on a train close to the main station in the city's financial district; minutes later the worst incident occurred: a bomb exploded in a deep underground line, killing more than twenty people. A third bomb on another underground train tore a hole through a tunnel wall, hurling debris onto an adjacent track and involving a further two trains. The fourth explosion ripped the roof off a bus.
The attacks were timed to cause maximum disruption during the morning rush hour, and with the underground network still shut down the city's workers are faced with a long walk home.
