The man accused of planting the Parsons Green bomb wanted to cause "maximum carnage" by planting a bomb on a rush-hour train, his trial has heard.
Jurors at the Old Bailey were also told that Iraqi asylum seeker Ahmed Hassan built the bomb using components bought on Amazon, before leaving it on the District Line train wrapped in a Lidl shopping bag last September.
Prosecutor Alison Morgan told the court that sharpnel was intended to fly out of the device when it detonate, and Hassan hoped this would cause "maximum harm and carnage to those in the surrounding area”.
Morgan told the court that Hassan had left the train by the time his device detonated, leaving several of the 93 people in the carriage with "significant burns."
“Many ran in fear and panic. They were fortunate," Morgan told the court.
"Had the device fully detonated, it is inevitable that serious injury and significant damage would have been caused within that carriage.
"Those in close proximity to the device may well have been killed.”
Hassan, from Sunbury-on-Thames, denies attempted murder and causing an explosion. The case continues.
