The BBC is inaccessible (probably the high network traffic).
This is what I see from the Times:
Blasts raise terror fears
# Co-ordinated blasts around London: dozens of casualties
# Blasts at or around these stations: Aldgate, Edgware Road, Kings Cross, Old Street, Russell Square in Central London
# Explosions on three buses: Tavistock Square and two unconfirmed locations
# Travel chaos as Underground closed
London explosions: timeline
By Holden Frith, Times Online
0849 BST: First explosion occurs on the Metropolitan Line between Liverpool Street and Aldgate
0922: King's Cross and Edgware Road stations evacuated
0928: Metronet, a Tube maintenance company, reports that the explosions have been caused by a power surge
0933: Explosion reported at Edgware Road
0951: Scotland Yard declare a "major incident" on the London Underground
1035: Metropolitan Police confirm that there has been an explosion on a bus in Tavistock Square, Central London
A series of bomb blasts that appeared to be a co-ordinated terrorist attack hit London's transport network today forcing police to close mainline stations and the entire underground system and causing dozens of injuries.
There were no confirmed reports of fatalities from three blasts on the Tube and a series of bomb attacks on London buses, but shaken commuters reported seeing bodies on a tube train at Aldgate and City of London police said it had unconfirmed reports of two deaths.
Transport union sources said three London buses had been hit by bomb blasts - including a double decker at Tavistock Square.
The blasts coincide with the first full day of the G8 summit in Gleneagles and come just one day after London won the right to host the 2012 Olymic Games. The number of near-simultaneous explosions bore the hallmarks of an al-Qaeda attack similar to the one that hit the Madrid railway network in March 2003.
A number of people were injured in an explosion at Aldgate station in the City at around 8.49am and the "walking wounded" were being taken to a nearby bus station for immediate treatment. Another explosion was reported at Edgware Road and another in the King's Cross area.
Geoff Hoon, leader of the House of Commons, told MPs that Cabinet ministers were meeting to discuss the situation and the Government would make a statement later.
Among mainline stations, Liverpool Street and King's Cross were closed and evacuated and services to others were interrupted.
British Transport Police (BTP) said that work was being carried out to establish the precise cause of the problem. "Its chaos, with people trying to work out what has happened," a spokesman said. "All we know at the moment is that staff reported a loud bang at 8.49am.
"No one is sure what caused an explosion, but it is thought it could have been a collision, a power cut, or a power cable problem."
A London Fire Brigade spokeswoman said: "We have been called to two explosions, one at Aldgate and one at Edgware Road. We have no other information at the moment. Reports are still coming in."
Transport union officials said their sources had told them there had been at least one explosive device on the Underground. One explosion happened at Edgware Road and there were suggestions of two other explosions at Kings Cross and Aldgate.
Union sources said they had been given the information by at least one senior Underground manager.
"It is too too early to state what has happened," a Metropolitan Police spokesman said."I cannot comment on reports of bombs, but we have had multi-reports of explosions around London."
Metronet, the company which maintains the infrastructure on the Metropolitan Line, said the explosion was caused by a power surge - althought the National Grid later denied that there had been any special surges. A Metronet spokesman said: "It looks as if we have a major incident. The whole system is being shut down."
Survivors of the Tube blasts described scenes of total chaos. Simon Corvett, 26, from Oxford, was on the eastbound train leaving Edgware Road Tube station when the explosion happened.
He said: "All of sudden there was this massive huge bang. It was absolutely deafening and all the windows shattered. The glass did not actually fall out of the windows, it just cracked. The train came to a grinding halt, everyone fell off their seats."
Mr Corvett, who works in public relations, said that the commuter train was absolutely packed. "There were just loads of people screaming and the carriages filled with smoke," he said. "You couldnt really breathe and you couldnt see what was happening. The driver came on the Tannoy and said We have got a problem, dont panic."
Sarah Reid, 23, a student doing work experience, was on the carriage next door to the one which was struck by the explosion at Aldgate. Speaking after the ordeal, having been led out down the track, near Liverpool Street station, she told how she saw a carriage ripped apart with the roof blown off.
"I think some people may have died," she said. "I was on the train and there was a fire outside the carriage window and then there was a sudden jolt which shook us forward. The explosion was behind me. Some people took charge. We went out of the back of the carriage.
Ms Reid said the explosion happened at 8.50am but she was not able to get off the carriage until 9.30am. Describing being led away from the scene, she said: "A carriage was split in two, all jagged, and without a roof, just open. I saw bodies, I think."
Sky News footage from Aldgate, in the heart of the City, showed commuters walking from the station covered in blood and soot and people being stretchered from the scene. At least a dozen fire engines were on the scene as nearby roads were closed off and offices evacuated.
Also closed were Liverpool Street mainline station in the City itself and the Kings Cross mainline station to the north. A British Transport Police (BTP) spokesman said that two trains remain stuck in tunnels at Edgware Road, but it is not known if they have collided or if passengers remain on board.
"Its difficult to know exactly what is going on at the moment," he said. "The initial report came from Liverpool Street, but there are incidents occurring across the network."
He said that officers have been sent into the network to assist with rescue operations."Officers are working at tunnel and platform level to help get people out and to help find out what has happened," he said.
One commuter whose train was diverted because of the chaos said travellers were told there had been a crash involving Tube trains near Kings Cross station.
"The area is solid with people and I have seen many commuters with blackened faces just walking around looking stunned," said Gerard Bithell. His train was diverted from Moorgate to Kings Cross because the station was closed. "We were told there had been a power failure at Moorgate and some kind of accident at Kings Cross," he said.
