7th July 2005
The first device exploded at 8.51am on a Circle line train between Aldgate East and Liverpool Street stations. Seven people were killed.
a second device exploded on a train between King's Cross and Russell Square, killing 21 people.
At 9.17am there was another blast on a train at Edgware Road station which blew a hole through a wall into another train on an adjoining platform. Two other trains were affected and seven people were killed.
At 9.47am a fourth blast blew the top off a doubledecker bus in Tavistock Square, central London, possibly killing more than a dozen people.
I have nothing to say except to ask "Why?".
