Sadiq Khan has said he will do “everything possible” to prevent a terror attack like the July 7 bombings happening again.

Speaking after a memorial event in London to mark the 11th anniversary of the London bombings, the mayor of London pledged to ensure the "resources and expertise" are put in place to respond to any future incident.

"Today we remember those we lost and the heroic efforts of our emergency services and transport colleagues on that darkest of days," he said.

“We must also ensure that every single individual, and every single agency, involved in protecting our city has the resources and expertise they need to respond to any future major incident.

"As mayor, my first priority is to do everything possible to prevent a tragedy like this from happening again."

Fifty-two people were killed and around 700 left with life-changing injuries when suicide bombers targeted three Underground trains and a bus in London on 7 July 2005.

Eleven years later around 200 members of the public, including about 100 survivors of the tragedy, attended the remembrance event held in Hyde Park to pay their respects.

A minute's silence was observed in memory of those who lost their lives and a single flower was laid at each pillar of the 7 July memorial.

Four survivors also spoke of their experiences. Thelma Stober, Jo McVey, Georgina Ferguson and David Smith each gave a moving account of how they were and still are affected by the tragedy.

Sudhesh Dahad, a survivor who works closely with the charity who organised the event, Foundation for Peace, felt comforted to see so many people at the event.

He told The Independent: "I feel very reassured that it isn’t forgotten. This is an important event in London’s history that should continue to be commemorated.

"It’s a warm feeling that people do still care about what happened".

Mr Dahad had been in the same carriage as the bomb on the Piccadilly line train. He survived with no severe physical injuries, but has been suffering from post-traumatic stress disorder.

He explained that as well as being an important way of commemorating the tragedy, the annual event can be a form of therapy for survivors still struggling to deal with what happened.

“There were quite a few survivors who had come for the first time. Some of them had suffered in silence and never spoken to anyone about it," he said.

"Speaking to others who experienced the same thing can be life-changing.”

During the memorial event, the Rock Choir performed and after the survivors had spoken the names of those who died were read out.

Foundation for Peace, which supports survivors of violent acts, worked in partnership with the Mayor of London’s Office and the families and survivors of the attacks to hold the memorial.
