A court in London began hearing inquests into the deaths of 52 people killed in a series of bombings that targeted London's transport network on July 7, 2005.

The inquiry will examine whether the police or the MI5 domestic intelligence service could have intercepted the bombers, two of whom had been under the surveillance of the authorities.
In the immediate aftermath of the bombings, officials stated that the four men - Mohammad Sidique Khan, Shehzad Tanweer, Hasib Hussain, and Germaine Lindsay - were unknown to authorities.
But in the years since the attacks, it was revealed that two of the bombers had been on the radar of the security services, but were not deemed significant threats.
Evidence at a number of court cases has shown that Tanweer and Khan, the organizers of the attacks, were photographed, recorded and followed by intelligence operatives several times in early 2004 in the company of plotters later jailed for planning other attacks using fertilizer-based bombs.
It concluded that the intelligence service could not have stopped the bombings because it lacked the resources to investigate Khan properly.
