The pictures show a cloud of dust and smoke filling a platform at Liverpool Street station seconds after a train was blown apart by suicide attacker Shezhad Tanweer , from Beeston, Leeds.

A court also saw the resulting chaos and horrified reaction of those near the No 30 bus in Tavistock Square when bomber Hasib Hussain, of Holbeck, detonated his rucksack.

The previously unreleased film was played to Kingston Crown Court where three men are standing trial accused of helping the bombers plan their attack.

The four bombers, Tanweer, Hussain, Mohammed Siddique Khan of Dewsbury, and Jermaine Lindsay, formerly of Huddersfield, murdered 52 people and injured hundreds more when they set off the devices in 2005.

The films were shown to the trial of Waheed Ali, 24, from Tower Hamlets, east London, Mohammed Shakil, 31, and Sadeer Saleem, 27, both from Beeston, who are accused of conspiring with the bombers to cause explosions between November 17, 2004 and July 8, 2005.

All three deny carrying out a two-day reconnaissance mission for the killers.

The trial continues.
