REPORTS of more bomb attacks on the London transport system have been confirmed by police.

Emergency services began receiving reports of "incidents" at three Tube stations shortly after 12.30pm.

Police evacuated Warren Street, Shepherd's Bush and Oval and cordoned off large areas around the stations.

British Transport Police confirmed that one person was injured at Warren Street.

There was also an incident on a number 26 bus at Hackney Road in Bethnal Green, where a minor blast blew the vehicle's windows out. There were no injuries.

Sir Ian Blair, Metropolitan Police Commissioner, confirmed that there were what appears to be a series of explosions or attempted explosions.

He described the incidents as "serious" and advised people in the capital to "stay where they are".

However, according to Sir Ian, the explosions were "smaller than on the last occasion".

One man has been arrested by police in Whitehall.

Five Tube lines - Victoria, Northern, Hammersmith and City, Bakerloo and Picadilly - were suspended. The Victoria line has since reopened either side of Warren Street.

Network Rail have confirmed that all mainline trains are running from London stations, although delays are expected.

Prime Minister Tony Blair has appeared on television and described the situation as "under control".

The Mayor of London, Ken Livingstone, said: "Londoners should now go about their business and use the transport system get home.

"I once more want to congratulate transport workers and the emergency services for their impressive efforts today and also the calm of Londoners."

It is two weeks to the day since a series of bomb blasts in the capital killed 56 and injured more than 700 people.
