The pictures show a cloud of dust and smoke that filled a platform at Liverpool Street station seconds after a train blown apart by suicide attacker Shezhad Tanweer had pulled away. Click the green play button to see the footage.

A court also saw the resulting chaos and horrified reaction of those near the No 30 bus in Tavistock Square when bomber Hasib Hussain 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 jury were also shown shocking photographs taken of the devastation caused to the tube trains and bus which were targeted.

The four suicide bombers, Tanweer, Hussain, Mohammed Siddique Khan and Jermaine Lindsay, murdered 52 people and injured hundreds more when they set off the homemade devices in the capital in 2005.

Tanweer's bomb killed seven other passengers when it tore apart the carriage of a Circle Line train heading towards Aldgate.

CCTV cameras at Liverpool Street capture commuters hurrying on to the train, where Tanweer is already waiting, as it pulls in to the platform.
Soon the busy platform is empty and the train pulls out of the station but just forty seconds later a flash is seen in the tunnel.

Clouds of dust then partially obscures the view of two cameras on both sides of the track before people still on the platform are seen running away leaving it deserted until police officers race to the scene.

Further footage from the reception of the British Medical Association building in Tavistock Square where 13 bus passengers were killed was also shown.

Two people chatting at the front desk are sent diving for cover by the impact of the blast. They struggle to their feet and hurry in the direction of the blast.

Others outside the building are seen in the background running away.
Pictures from a bus which was just ahead of the No.30 show panicking passengers jumping out of their seats in shock and struggling to get off the bus when the vehicle behind them explodes.

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, Leeds, who are accused of conspiring with Khan, Tanweer, Lindsay, Hussain and others unknown to cause explosions between November 17, 2004 and July 8, 2005.

All three are alleged to have carried out a previous two-day reconnaissance mission in the capital on December 16 and 17, 2004 with Hussain and Lindsay. The defendants deny the charge.

The jury first saw pictures of the journey the men made from their homes in Leeds and Aylesbury to Luton railway station on the morning of July 7. Click here to see the footage.

Grainy black and white pictures show the four gathering around the boot of a hired Nissan Micra car in the car park where they put on the rucksacks containing the bombs.

The four then pass through the ticket barriers at Luton station and mingle with other passengers on the platform.

The court was shown the last sighting of the four together as they arrive at King Cross Thameslink in London before disappearing into the underground system.

The first of the four bombs, detonated by Khan, killed six of his fellow travellers on a Circle Line train between Edgware Road and Paddington.

The jury was shown a picture of the mangled wreckage of the train with the doors and windows blown off and the interior charred and blackened.
Similar pictures of the train blown up by Tanweer showed the same devastation with blood stains on the floor.

The device exploded by Lindsay murdered 26 passengers on a Piccadilly Line train between Kings Cross and Russell Square. Pictures showed only one side of the train remaining following the blast.

The jury also watched the movements of Hasib Hussain caught on CCTV who seems to have suffered a technical hitch with his bomb. He is seen bending over his rucksack and then buying an item, believed to be a battery, from WH Smith.

Wearing sunglasses, he mingles with passers-by on the busy streets outside Kings Cross tube before he finally disappears from the cameras' view.

Statements from witnesses who saw Hussain in the minutes before he detonated his device were read to the court in which he was described as being agitated and "sweating profusely", knocking past other passengers as he took his seat at the back of the bus.

The court was told that mobile phones belonging to Khan and Lindsay were found during searches of the blast sites.

On Khan's phone he had numbers saved for both Shakil and Saleem. A number for Ali was found on Lindsay's mobile.

The jury were earlier shown more footage caught on CCTV cameras of three of the bombers carrying out a reconnaissance trip to London nine days before the July 7 attack.

Khan, Tanweer and Lindsay spent four hours in the capital, visiting various locations on the Underground network on June 28.

They were captured on security cameras meeting at Luton railway station before journeying to King's Cross and then on to Tube stations at Embankment, South Kensington and Baker Street.

The court was shown clips of the trio mingling with commuters, buying tickets and travelling up and down escalators on the transport network.
At one point ringleader Khan, wearing a baseball cap and rucksack, is seen strolling towards Madame Tussauds and then minutes later casually eating an ice-cream.

The trial was adjourned until tomorrow.
