Details of the identities of the four individuals responsible for the bombings of 7 July 2005 is contained in the Intelligence and Security Committee's report: Review of the Intelligence on the London Terrorist Attacks on 7 July 2005. The four were identified as Mohammed Siddique Khan, Shazad Tanweer, Jermaine Lindsay and Hasib Hussain. It is considered that none of these individuals worked on behalf of another country. Although al-Qaeda claimed responsibility for the attacks, there is as yet no firm evidence to corroborate this claim. However, the target and mode of attack of the 7 July bombings are typical of al-Qaeda and those inspired by its ideologies.
The ISC has commented in its second report that “it has become clear, since 7/7, that Mohammed Siddique KHAN had been training in Pakistan (on at least two occasions) and also possibly in Afghanistan”.
