Mayor of London Sadiq Khan and Metropolitan Police Commissioner Dame Cressida Dick have paid tribute to the 52 people who died in the July 7 bombings, on the 15th anniversary of the terror attacks.

A series of explosions ripped through London in co-ordinated terrorist strikes in 2005.

The attacks on three London Underground trains and a double-decker bus killed 52 people as well as the bombers, and more than 700 people were injured.

Dame Cressida and Mr Khan laid wreaths at the 7/7 memorial in Hyde Park at 8.50am on Tuesday morning – the time of the first bomb.

A message on the wreath laid by Mr Khan said: “Fifteen years have passed, but the 52 innocent people who lost their lives on 7/7 remain in our hearts.

“Those who seek to divide our communities and destroy our way of life will never, ever, succeed.”

Dame Cressida paid tribute to the people “cruelly snatched away” as well as survivors whose lives were “turned upside down” by injuries.

“Those we lost represented the best of our city – diverse, strong, wonderful people,” she said.

“As a city, London was not bowed, we came together, we supported each other and we have continued to fight the scourge of terrorism ever since.

“Today, I think also of my officers and staff who ran towards those terrible scenes. Who put themselves in danger and tried to do their best to support those affected.

“On behalf of everybody in the Metropolitan Police Service, we will not forget.”

In a video message, the Prince of Wales offered his thoughts: “For all of us today is an occasion to remember those who were so tragically lost and to stand with those who were left behind.

“It is also an opportunity to reaffirm our shared determination that tolerance and compassion will triumph over division and hatred, and that hope will always prevail.”

British Transport Police Chief Constable Paul Crowther, City of London Police Commissioner Ian Dyson, and Mike Brown, Commissioner for Transport for London, were also among those who paid tribute to the victims.

A second group, including London Fire Brigade Commissioner Andy Roe and London Ambulance Service’s director of integrated patient care, Athar Khan, laid wreaths at 9.47am, the time of the bomb on the bus in Tavistock Square.

A floral tribute was sent by Prime Minister Boris Johnson, while a separate virtual service for families of the 52 people who died and the survivors is being held on Tuesday afternoon.

Paralympian Martine Wright, who lost both her legs in the Aldgate explosion, tweeted: “15 yrs ago I jumped on a circle line tube and it changed my life forever.

“Remembering all those affected by #londonbombings all those that risked their lives helping others and all 52 souls that lost their lives.

“My thoughts are with them and their families today and everyday.”

The way that our city responded and stood united in the aftermath of the attack showed the world that our values of decency, tolerance and mutual respect will always overcome the hate of the terrorists

Mr Khan said: “Today we honour the 52 people who lost their lives and more than 700 who were injured on July 7 2005.

“Our capital will never forget the terrible events of that day, and my thoughts are with all those whose lives were changed forever.

“As we mark 15 years since the attack on our city, I want again to pay tribute to the heroic efforts of our emergency services and transport workers, who ran towards danger to save lives, on that awful day.

“The way that our city responded and stood united in the aftermath of the attack showed the world that our values of decency, tolerance and mutual respect will always overcome the hate of the terrorists.

“Today, we reaffirm our commitment to upholding these values. To those who wish to divide us and spread hatred, we send a clear message that they will never succeed, and that we are stronger together.”

Mr Brown said: “We will never forget those innocent victims who lost their lives in the most tragic circumstances 15 years ago.

“We stand united with our colleagues from the emergency services and the city as a whole in remembering them today.

“The resilience of great world cities like ours continues to be tested but Londoners have shown time and time again that our strength lies in our diversity, resourcefulness and spirit of togetherness.”
