From the BBC at 11:23:
Metropolitan Police Commissioner Sir Ian Blair said there had been at least six
explosions, but said the picture was still "very confused".
I've tracked down one of the missing co-workers. Her fiance called to say she was okay, but she was in the train behind one of the ones with an explosion.
That's cutting a little too close to home.
There are reports on the radio saying that there are 20 confirmed dead, and at least 90 injured at Aldgate station.
There are no buses or tubes running in central London at all, and the army is present in Covent Garden.
