MI5 is said to have to have gained intelligence four months before the 7/7 bombings which could have identified the ring leader but they failed to do anything.
Inquests have heard that MI5 could have identified Mohammad Sidique Khan as an extremist, but information was not followed up for good operational reasons, MI5’s chief of staff, known as witness G, argued.
A report about an extremist called “Saddique” was received in March 2005.
Families of the 52 victims that lost their lives in the 2005 London attacks are beginning to question Witness G.
After four suicide bombers detonated their devices on three underground tube trains and one double-decker bus on 7 July, 2005, many relatives of the victims want to know why those under surveillance were not subject to thorough investigation.
On Monday Witness G provided a statement protecting the MI5 suggesting that the security service could not be held responsible for the attacks. Witness G also said that MI5 were aware of many individuals involved in Islamist extremism but urged that this was not the same as planning terrorist attacks.
Specifically, they knew that many of these people took apart in “Jihadi tourism” during which they would go to Pakistan to have a look around.
Witness G said: “Being an interesting target does not necessarily mean that he would have a high proportion of surveillance resources thrown at him”
Witness G added that the decision had been taken not to further investigate the real identity of “Saddique” for good operational reasons – but he insisted that it was impossible for him to explain the decision because of national security reasons.
