British Prime Minister Gordon Brown has joined survivors and relatives of the victims killed in the July 7th bombings in London in a low-key sombre act of remembrance to mark the second anniversary of the attack.
Some 52 people died and hundreds were injured in four bomb attacks on London buses and underground trains.
Before families and friends laid their own tributes, Mr Brown led a small procession to lay wreaths in the memorial garden beside King's Cross Station at the exact time the first bomb struck two years ago.
The Prime Minister, former Culture Secretary Tessa Jowell, London Mayor Ken Livingston, Transport Commissioner Peter Hendy, Tim O'Toole of London Underground and the Mayor of Paris, Bertrand Delanoe, all bowed their heads in silence for several minutes before making way for survivors and relatives to pay their respects.
A short message attached to the flowers Mr Brown laid read: "In remembrance and with deepest sympathy".
