7/7 bombings: 'Ocean of pain' as victims of London attack remembered on 10-year anniversary
A memorial service at St Paul's Cathedral has marked the 10th anniversary of the London bombings.
The families of those who died in the attacks were in attendance, as well as some of those injured on July 7, 2005.
Prayers were led by priests who helped minister people in the hours and days after the blasts.
Candles representing the site of each incident were carried by people who helped deal with the immediate aftermath.
They included George Psaradakis, who was driving the bombed bus at Tavistock Square, and Dr Peter Holden, who provided urgent treatment at the scene.
Guests at the service included the Duke of York, Prime Minister David Cameron, mayor of London Boris Johnson and his wife Marina, former prime minister Tony Blair and his wife Cherie, Home Secretary Theresa May and Metropolitan Police Commissioner Sir Bernard Hogan-Howe.
The names of the 52 victims were read out before a minute of silence was held and petals were released from the dome.
The Bishop of London, Richard Chartres, gave an address.
He said: "Soon after 7/7 the families and friends of the victims compiled a book of tributes.
"It is a taste of the ocean of pain surrounding the loss of each one of the victims.
"The tribute book is also very revealing about the character of the London which the bombers attacked.
"The majority of the victims were young. They came from all over the UK and all over the world."
The service also featured reflections of the blast sites.
David Boyce, who was one of the first London Underground staff to realise a bomb had exploded near Russell Square, described how the area is home to the British Museum, the University of London, and is also a place where T S Eliot worked.
He said: "Here, men and women seek understanding and their search for truth challenges the ignorance which casts so much darkness over our world."London Fire Brigade commissioner Ron Dobson described the service as "wonderful" and "a really fitting tribute".
He said: "It's entirely appropriate that London takes a moment of reflection to think about those that were injured and killed on that terrible day, because London has moved on.
"London is an incredibly vibrant and resilient city. London carries on with its business as it always should. 'But it is appropriate to have a moment of reflection."
British Transport Police Chief Constable Paul Crowther, who was in charge of London Underground policing on July 7, said: "The service was incredibly moving and an absolutely fitting tribute to the victims of the attack, also the survivors and the very many people who responded to help those in need."
He added: "We should never forget 52 people perished in this terrible attack."
