Two men have been arrested by armed police in London after four small blasts or attempts at blasts which have disrupted the capital but brought no significant casualties. One man was held near Downing Street and taken away by car. The other was arrested at Great Scotland Yard, a side street nearby.
London endured another smack in the face today, when three Underground stations were evacuated at midday following reports of smoke and explosions.
The incident happened just two weeks after the July 7 attacks that took the lives of more than 54 people in a morning rush hour. Police are also investigating a report of an incident on a bus in east London.
British media have reported that three tube stations including Warren Street, Oval and Shepherd's Bush were evacuated.
Smoke has been seen coming from Oval station, which crews are investigating. There are unconfirmed reports of some kind of explosion at Warren Street station.
Emergency services are attending all three stations. The Hammersmith & City, Victoria and Northern tube lines have been closed.
BBC reported that minor explosions using detonators only have sparked the evacuation of the three tube stations and the closure of three lines.
A route 26 bus in Hackney Road in Bethnal Green had its windows blown out by a blast with no reported casualties, added the newspaper.
However, Andrew Winstanley, the BBC correspondent, said that one person was injured at Warren Street, although the person's condition is unknown.
Police in London say they are not treating the explosions as "a major incident yet".
At Shepherd's Bush station, police told reporters that a man had threatened to blow himself up and then ran off.
Some witnesses said they heard gunshots at Warren Street and saw an assailant running from the scene, but Scotland Yard sources said it was unclear if the noise was from gunfire or detonating caps.
Downing Street said that, given the uncertainty surrounding events, the prime minister, Tony Blair, had cancelled a visit to a school in east London this afternoon. He had been due to meet security chiefs to discuss the July 7 attacks later today.
The Metropolitan police had warned of a risk of further attacks, following the July 7 bombings.
Hunt for third suspect
Police are probing clues among the remains of explosive materials after the blasts.
A police van believed to contain a third suspect has driven off from University College Hospital in central London, near to Warren Street.
But Tony Blair revealed that the arrests made this afternoon are not connected with the bomb attacks.
He did confirm that some forensic material has been recovered from the scene of the blasts.
