Reports are just coming in on the BBC of four emergency "incidents" on the London Underground and on one bus in Hackney, East London. The three underground stations, now being evacuated, are Warren Street, The Oval, and Shepherd's Bush, and at least three underground lines corresponding to these lines have been closed.

East, central, and west London are affected.

JUST IN -- A police sergeant reports to the BBC that there has been an explosion in one of the underground stations.
