"Jurors were shown never-before-seen CCTV footage of those attacks, tracking their movements from the moment the four bombers met in Luton, to the moment they detonated their bombs."

"The prosecution went on to show the jury CCTV footage of the events of 7 July 2005, the first time the material had been seen other than by police and security services.
The footage captured the four bombers assembling in the early hours of the morning and heading to Luton railway station.
In the grainy CCTV images, time-stamped at 0716, the men could be seen opening the boot of a car in the main station car park, pulling on the rucksacks containing their bombs and walking to a platform to take a commuter train to London.
The CCTV footage continued as the men disembarked at Kings Cross Thameslink, before getting on the London Underground to head towards their targets.
Jurors were then shown images of the damage caused by Khan's bomb, which ripped through the carriage of a westbound Circle Line train shortly after it left Edgware Road, killing him and six other passengers.
CCTV footage also showed a Circle Line train leaving Liverpool Street station and, as Tanweer detonated his device, smoke filling the platform leaving commuters running for cover. He killed himself and seven other people.
Stills of the remains of the Piccadilly Line train, after the third bomber, Lindsay, exploded his device killing another 26 passengers, were also shown.
CCTV footage also captured bus bomber Hussain, who it is claimed had problems with his rucksack bomb, at a WH Smith newsagents where it is believed he bought a new battery.
He went on to detonate his rucksack shortly before 10am on the upper deck of a number 30 bus in Tavistock Square, killing him and 13 other people."
