Prosecution key points: Day Seven

All six deny conspiracy to murder

Further witnesses in the case against six men accused of a plot to blow up parts of London's public transport system have appeared in court.

Muktar Ibrahim, Manfo Asiedu, Hussein Osman, Yassin Omar, Ramzi Mohammed and Adel Yahya deny conspiracy to murder and conspiracy to cause explosions.

On the seventh day of the trial, Woolwich Crown Court was shown dramatic CCTV footage of an alleged attempt to set off a bomb on a Tube train on 21 July 2005.

The film pictures one of the alleged bombers, Ramzi Mohammed, getting on the northbound Northern Line train, and a bang taking place between Stockwell and Oval stations.

Witnesses for the prosecution told the court that Mr Mohammed tried to set off a rucksack bomb on a Tube train.

Nadia Baro, on the train with her nine-month-old son, said she noticed the person next to her was wearing a rucksack. Then she heard a bang and something came out of the bag and fell onto the floor.

She described the substance coming from the rucksack as being like a sponge or foam with "bits of nails on it", and she noticed something "like the smell of oil".

Ms Baro told the court: "I was in such a panic. I did not know how a bomb worked and I thought we were going to die now."

Angus Campbell told court he confronted Mr Mohammed, who he said tried to set off a rucksack bomb in front of him.

Mr Campbell, a firefighting instructor who served as a firefighter for 21 years, told the jury he saw Mr Mohammed with "smoke issuing from behind him" and shouted at him "what have you done?".

The court also heard that several members of the public, including a 72-year-old former soldier, chased the alleged bomber at Oval station.
