A permanent memorial to the victims of London’s 7/7 attacks has been unveiled on the fourth anniversary of the bombings.Prince Charles laid a wreath on behalf of the nation at a ceremony at London’s Hyde Park. The memorial takes the shape of 52 steel pillars – one for each of those who lost their lives – and a plaque bearing their names. “The families of the victims, the survivors, and the stout-hearted emergency services remain very much in our thoughts and prayers. You are a moving example of holding together bravely in the face of such an inhuman and deplorable outrage,” said Prince Charles. After a minute’s silence, the name of each victim was read out. They were killed when suicide bombers detonated explosives on a bus and three underground trains across the capital. The bombers, all British Muslims, were opposed to Britain’s involvement in Iraq.
