7/7 surveillance report clears MI5
Updated on 19 May 2009
A parliamentary intelligence report refrains from criticising MI5's decisions before the 7/7 attacks, but says it is "astounding" that MI5 could only adequately monitor one in 20 terror suspects.
The July 7 attacks killed 52 innocent people in 2005, and hundreds more were injured when four suicide bombers blew themselves up on London's transport system.
Three and a half years later survivors and the victims' families still have questions about whether security services and police could have done more to prevent the attack.
At the time the bombers were thought to be "clean skins" previously unknown to security services, but it has since been revealed two of them had been on the intelligence radar for more than a year.
