Chief executive of the Aslef train drivers' union, external Keith Richmond says: "Today our thoughts are with the victims of those attacks, and their families, and with all those who work on London's public transport system, and the emergency services, who did all they could to help 10 years ago."

Unity has been the resounding message of the service at St Paul's Cathedral.

"Beyond the numbing shock of what happened, there was solidarity. There was unity in our grieving," the Bishop of London Richard Chartres said in his address.

There is truth in his statement. Many of the relatives and survivors in the congregation - strangers until their lives were suddenly welded together by the blasts - have become firm friends, and a vital source of support for each other over the last decade.

Leaders of all faiths pledged to stand united in the face of terrorism.

A peal of bells marked the close of the service at midday.

It was fitting that this significant anniversary be marked in St Paul's, whose dome came to symbolise Londoners' ability to pull together and go on during the Blitz

In Leeds, where three of four bombers lived, lord mayor Judith Chapman led the silent tribute at 11:30, saying: "They did not represent this city 10 years ago and they do not represent it now."

Police officers gathered within the grounds of Wimbledon Tennis Club to observe a minute silence to commemorate the tenth anniversary of the 7 July 2005 London terrorist attacks.

The service of commemoration at St Paul's Cathedral is drawing to a close with prayers led by Reverend James Milne, and other clergy, including some who ministered to people affected by the events of 7 July 2005.

The father of one of the victims says he thinks about his son every day.

Philip Russell, 28, a financier from Kennington, south London, died in the Tavistock Square explosion.

Speaking to the BBC's Victoria Derbyshire at the site of the attack, Graham Russell, said: "Time does not heal. All it does is put the event further into the past. You never get closure. It's just that that scar has a thin veneer over it and every so often it breaks up."

Met Police Commissioner Sir Bernard Hogan Howe tells BBC London 94.9: "Looking back after all these years, the first thing we think about is the families of the 52 people who were murdered.

"There were 4 murderers that day. We've got to remain eternally vigilant that does not happen again.

"We've got to be vigilant. We've got to be prepared."

Others in attendance at the service included former Prime Minister Tony Blair and Ken Livingstone, London Mayor at the time of the attacks.

The Bishop of London, The Right Reverend Richard Chartres, reminded the service of the book of tributes to the victims set up after 7 July 2005. It reflected the capital's diversity and make up, he said.

"There could have been so easily been a demonstration of anger but beyond the shock there was solidarity," he said.

The story of how the residents coped and acted "deserves to be woven into the consciousness of London's memory," he added.

The service is continuing with the names of all 52 people killed on 7 July 2005 being read out.

The minute's silence will follow at 11:30, and then petals will be released from the dome of St Paul's.

Staff from Transport from London, the ambulance service, police and fire brigade gave readings at the St Paul's service, reflecting on the history of the four sites hit by the attacks.

They were followed by a reading by a young Londoner, Aaron Grant-Booker.

"These four pieces of London epitomise what is great about this city," he said.

"When four bombs exploded on 7 July 2005, lives were destroyed and the flame of hope faltered for what seemed like an eternal moment.

"For many people, nothing was the same again and yet everything was the same because the good which is in Londoners and the countless visitors whom they host at any given moment is not erased by hatred or threat but, rather, is fostered to produce a harvest of hope for each generation."

A reading from the New Testament at St Paul's Cathedral by London Mayor Boris Johnson is followed by a procession by representatives from the emergency services.

Candles placed earlier this morning at the site of each bombing are being carried through the cathedral and placed under its famous dome before the altar.

Mohammed Shafiq, chief executive of the Ramadhan Foundation, external, says: "Today ten years on from the 7/7 terrorist attacks we remember all those killed and injured and their loved ones.

"They were killed by evil men who were driven by hate and a poisonous ideology, which has distorted Islamic teachings.

"British Muslims stood with the victims on that day and do so again today," he added. "We reject this terrorism and ideology and commit ourselves to work with all to protect the safety and security of our country and fellow citizens."

The dean added: "Here, in this icon of the London skyline, we celebrate our city and our community, with its people's tolerance of difference and their respect for diversity...

"But we recall too our shortcomings and failings."

The Duke of York, who is representing the Queen at the service, was received at the Great West Door by the Chapter and the Bishop of London.

The Dean of St Paul's The Very Reverend Dr David Ison, told the service that "representatives of this city and of this nation, together with friends from around the world" were gathering "to recall a moment in time when lives were destroyed and the world was changed".
