Failed bomb on London Tube could have been fatal, trial told

The Parsons Green bomb packed with 400g of explosives and shrapnel could have been lethal if it had fully detonated, an expert has said.

Iraqi asylum seeker Ahmed Hassan (aged 18) allegedly used a "student of the year" prize to buy a key ingredient for the device on Amazon and assembled it in the kitchen of his foster home in Sunbury, Surrey.
