Dramatic new video footage was shown to a court today of the moments two of the 2005 July 7th bombers detonated their devices in London.
The previously unseen closed circuit television camera footage was released publicly for the first time at the trial of three men accused of helping the bombers plot their attacks.
Mohammad Sidique Khan, Shehzad Tanweer, Jermaine Lindsay and Hasib Hussain killed 52 people and injured hundreds more in the co-ordinated morning rush hour attacks on three underground trains and a bus.
Today the jury at Kingston Crown Court was shown the moments two of the bombings occurred, a scouting mission by three of the bombers throughout London's transport network nine days before the attacks and photographs of the extensive damage the blasts caused.
In one example, taken from closed circuit television cameras at the British Medical Association building, the moments as Hussain detonated a bomb on the Number 30 bus in Tavistock Square, central London is shown.
The footage later showed terrified people cower as it exploded just before 10am, killing Hussain and 13 others before they try and flee the scene.
In another, CCTV on the bus in front showed panicked people jumping out of their seats as the bus explodes.
Another film shows the moments as Tanweer detonated his bomb on an eastbound Circle Line train that killed the bomber and seven commuters.
The packed train approaches the platform at Liverpool St where commuters enter then, about 40 seconds later as the train approaches Aldgate, the platform fills with smoke and dust after Tanweer's bomb exploded.
Prosecutors say that between November 17th, 2004 and July 8th, 2005, Waheed Ali (24) Mohammed Shakil (31) and Sadeer Saleem (27) "unlawfully and maliciously" conspired with the four bombers and others unknown to cause explosions likely to endanger life or cause serious harm and injury.
The court has already been told the men, from Beeston, Leeds, helped the bombers scout for potential targets in the capital.
During a reconnaissance weekend seven months before the bombings, two of the accused visited the London Eye, the Natural History Museum and the London Aquarium, prosecutors said.
The court has also heard the men had extensive contact with the bombers, which had been uncovered through mobile records, fingerprints on documents, family videos and surveillance.
They all deny a charge of conspiracy to cause explosions and say that although they knew the bombers, their friendship was innocent.
The trial continues.
