BLASTS ON TUBES AND BUS
According to reports a bus has exploded in central London just minutes after a number of blasts on London's Underground.
"I saw lots of people running up a road and then saw the top of a bus destroyed," one eyewitness told Sky News.
Sky News producer Bob Mills said he heard the loud explosion near Euston Station.
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".
