Today marks the 7th anniversary of the 7th July 2005 London bombings (often referred to as 7/7).

A small ceremony was held in Hyde Park for the families of the victims to remember those who lost their lives.

Four terrorists detonated bombs in the morning rush-hour, three on the underground railway and a fourth in Tavistock Square on board a double-decker bus.

Fifty-two people, as well as the four bombers, were killed in the attacks, and over 700 more were injured.

Wreaths have been laid on behalf of Prime Minister David Cameron and Mayor of London Boris Johnson at the Hyde Park memorial to the victims. A minute's silence is set to be observed at a meeting at City Hall this evening.
