The London police commissioner confirmed that four explosions occurred in the subway and on a bus in the Hackney neighborhood of East London. None of the explosions appear to have detonated properly. Officials are hoping that the left-over explosives will provide a wealth of forensic evidence to help investigators hunt down the bombers.

One Sky News reporter on the ground said officials said the explosive device on the bus appears to be the same type used in the July 7 bombings in London. The material is highly explosive, which is why such a large area around the bus has been cordoned off. Police also said an armed police unit had entered University College hospital. Press Association, the British news agency, said they arrived shortly after an injured person was carried in. Sky News TV reported that police were searching for a man with a blue shirt with wires protruding. Officers asked employees to look for a black or Asian male, 6 feet 2 inches tall, wearing a blue top with a hole in the back and wires protruding.
