An explosion has "ripped a bus apart" just minutes after a number of blasts on London's Underground.Scotland Yard has confirmed there has been an explosion on a bus in Tavistock Place. Union sources claim there have been reports of blasts on three different buses.
Witness Belinda Seabrook said she saw an explosion rip though a bus as it approached Russell Square.
"I was on the bus in front and heard an incredible bang. I turned round and half the double decker bus was in the air," she said.
Another witness, Angie, told Sky news: "There were a whole lot of people around the bus. Next thing I was on the floor and there were a lot of people on me.
"I thought I was going to be crushed. The bus was ripped out at the back. It must have been a bomb."
Scotland Yard could not confirm reports of an explosion on a bus in Russell Square. A spokeswoman said police were at the scene and attempting to determine what had happened.
The entire Tube network has been shut down following the blasts at Aldgate, Edgware Road, King's Cross, Old Street and Russell Square.
It is understood several people have been wounded in the underground blasts, with one unconfirmed eyewitness telling Sky News he saw "bodies on the line".
British Transport Police confirmed there are "walking wounded" and said paramedics have responded to one report of a person classed as "life at risk".
"It's chaos, with people trying to work out what has happened," said a spokesman.
One witness said the packed underground train he was on was 200 metres from King's Cross when there was a huge flash.
The train stopped and people were using umberellas to smash windows of the trains. Passengers were led out of the train by underground staff.
He added people were milling around King's Cross covered in soot.
Clare Benson, 33, a city banker from Kensington, was on a tube at Edware Road where the second incident took place.
"I was in the last carriage at the back of the train nearest the tunnel when I heard a huge bang - you could feel it," she said.
"The lights went off for a couple of minutes and people were scared and wondering what to do.
"The drivers got out and were looking into the tunnel, then they announced that we should evacuate. My ears are still ringing and I was shaking."
Union sources said they had received reports of explosions on three buses in central London.
London Fire Brigade said it had been called to reports of "explosions" at a number of locations in central London, including Aldgate, Edgware Road and Tavistock Square as well as another incident at King's Cross.
A Scotland Yard spokeswoman said the reports of explosions in Edgware Road, King's Cross, Liverpool Street, Russell Square, Aldgate East and Moorgate were all at underground stations. She said that so far, there was only one confirmed explosion on a bus.
Paul Tripea, owner of the Russell Square Cafe, said people had rushed inside following an explosion.
"One of the security guards from a nearby hotel rushed in and said he saw the bus explode around Tavistock Square," said Mr Tripea.
"We have also heard that there is a suspect package in Russell Square.
