LONDON mayor Sadiq Khan on Sunday (7) paid tributes to the victims of the 7/7 bombings on the 14th anniversary of the attacks in London.

Khan stood side-by-side with chiefs of the Metropolitan Police, British Transport Police and City of London Police and laid flowers at a 7/7 memorial.

Fifty-two people were killed and dozens injured on July 7, 2005 when suicide bombers targeted innocent people on their way to work in central London.

Speaking at the event, Khan said: “Today we honour the 52 people who tragically lost their lives 14 years ago in the terrible attacks on our city,” he said.

“We will never forget those innocent victims, and as we grieve for them we also pay tribute to the heroic efforts of the emergency services and first responders who selflessly ran towards danger to help others.

“Londoners showed resilience and unity in the face of huge adversity in 2005, and sadly our city has faced difficult times since then.

“But, standing together, we uphold the values that make this the best city in the world, united in defiance against terrorism.”

Home secretary Sajid Javid also paid his respects.

Taking to Twitter, he wrote: “We will never forget the 52 lives that were lost & the hundreds injured in the 7/7 attacks. Fourteen years on, our strength & resolve in the fight against terror remains undimmed. #WeStandTogether.”

On the day of the attack, three suicide bombers set off from Leeds, West Yorkshire to pick up their accomplice in Luton, Bedfordshire.

They arrived at London King’s Cross station at 8.23 am carrying rucksacks packed with explosives. Three bombs were detonated on board London Underground trains within 50 seconds of each other. The fourth attack happened on a bus about an hour after the other explosions.
