7 July 2005 London bombings
The first bomb exploded on a train that was travelling below the ground, going towards the east between Liverpool Street and Aldgate. The train had left King's Cross St Pancras about eight minutes before. When the explosion happened, the train's third carriage was about 100yards (90m) along the tunnel from Liverpool Street. The parallel track of the Hammersmith & City line between Liverpool Street and Aldgate East was also damaged in the blast.
