The jury in the trial of a man accused of carrying out a bomb attack on a London tube line last year has been shown dramatic CCTV footage of the explosion.
The video, released by the Metropolitan Police, shows a huge fireball filling the crowded train in Parson Green on the morning of September 15.

The Old Bailey heard how 18-year-old Ahmed Hassan used a £20 voucher he won as ‘student of the year’ at Brooklands college, London, to buy chemicals to make the explosive device.
The Iraqi asylum seeker allegedly made the bomb at home while his foster parents were away on holiday.
After filling it with 2.2kg of shrapnel, he concealed it in a Lidl bag and left it on the floor of the rush-hour train before getting off and activating it at the next stop, the court was told.
Experts said it was simply "luck" that the device only partially exploded, sparing the lives of 93 commuters on the packed carriage.
The teenager told Home Office officials in January 2016 that he was kidnapped by ISIL and "trained to kill", fearing his family would be killed if he resisted, the prosecution said.
Hassan denies attempted murder and using the chemical compound triacetone triperoxide (TATP) to cause an explosion likely to endanger life.
The trial is ongoing.
