Several people have been injured after explosions on the Underground network and a double-decker bus in London.

A police spokesman said there were "quite a large number of casualties" at Aldgate Tube Station.

And Scotland Yard confirmed one of several reports of explosions on buses in the city - in Tavistock Place - but said the cause was not yet known.

UK Home Secretary Charles Clarke said several explosions in central London had caused "terrible injuries".

"The health services are in support to deal with the terrible injuries that there have been," Clarke told reporters outside Downing Street.

Number 10 said it was "still unsure" whether the explosions were a terrorist attack and although casualties were reported, no further details were yet available.

Ministers are meeting to clarify the situation and the government will make a statement later, Leader of the House Geoff Hoon told the Commons.

One caller to BBC Five said his friend had seen "the bus ripped open like a can of sardines and bodies everywhere".

And PA quoted union officials as saying sources had told them there had been at least one explosive device on the Underground.

British Transport Police said incidents took place at Aldgate, Edgware Road, King's Cross, Old Street and Russell Square stations.

Scotland Yard confirmed they were assisting with a "major incident" and said there were casualties.

Hospitals have said they are no longer accepting non-emergency cases, BBC Five Live reported.

The National Grid, which supplies power to the Underground, said there had been no problems with its system which could have contributed to the incidents.
