London attackers 'meant to kill'
The people behind the latest attacks in London meant to kill, the head of the Metropolitan Police has said.
But Sir Ian Blair said evidence left at the scenes could be very helpful to police and added "the intention of the terrorists has failed".
Attempts were made to set off explosives at four locations, including three Tube stations and on one bus.
Sir Ian said the ambulance service had not taken anyone to hospital after the blasts, which were almost simultaneous.
Mayor Ken Livingstone praised the emergency services and said the people of London would "get through this".
'Unexploded' devices
Sir Ian said there was a "resonance" with the bomb attacks which killed 56 people two weeks ago, but that it was too early to draw any conclusions about whether they were linked.

Police forensic experts are examining the scenes, at Tube stations in Oval, Warren Street and Shepherd's Bush, and on a bus in Shoreditch, east London.
He said important information could be recovered. "From what I understand, some of the devices remain unexploded," he said.
The Met commissioner warned against "smearing" any particular community with the blame for Thursday's attacks.
"These are criminal acts and we are in pursuit of a set of criminals," he said.
'Difficult day'
He said it had been "another difficult day" for Londoners, but that the city was already "back to business".
Ken Livingstone said: "It is not surprising that we have had another attempt to take life rapidly after the first attacks.
"Those people whose memories stretch back to the 70s, 80s and 90s will remember there were horrifying bombing campaigns in London. We got through that and we'll get through this."
Mr Livingstone backed a police appeal for information on who may have been behind the attacks.
He said religious leaders should remind their congregations of the immorality of what had happened and that people should come forward even if the was only "a remote possibility" that they could help catch those to blame.
