More than 50 killed in London attacks

Metropolitan Police Commissioner Ian Blair has said in London that more than 50 people were killed in yesterday's terror attacks.

Commissioner Blair said there was "great difficulty in determining how many fatalities" there were because of the damage at the scenes.`

He added that there were 700 casualties, 350 people were taken to hospital, 22 are still in a critical condition and one person died in hospital.

The commissioner said there was "absolutely nothing to suggest that this was a suicide bombing attack although nothing at this stage can be ruled out".

Meanwhile, anti-terrorist branch head Andy Hayman said each of the bombs contained less than 10lbs of high explosives and they were probably placed on the floor or, in the case of the bus, on the floor or a seat.
