Prince Charles has paid tribute to the families who lost loved ones in the 7 July 2005 London bombings, at a memorial in Hyde Park.
He said that their bravery "offered us hope for the future".
Prime Minister Gordon Brown and Minister for London Tessa Jowell joined the Prince of Wales at the unveiling of the 52 steel pillars.
Fifty-two people died after suicide bombers detonated explosives on board three Underground trains and a bus.
The victims’ relatives at the unveiling said the permanent memorial, between the park’s Lover’s Walk and Park Lane, was a "fitting tribute".
