People across London were encouraged on Tuesday to participate in "Walk Together" in memory of the victims of the 2005 terrorist attacks in the city.
The campaign, organised by the think tank British Future, urged commuters on the way to work to get off public transport a few stops earlier and walk the rest of the way, in remembrance of the victims of the attack.
The attacks, which took place on key areas in London's public transport network, claimed the lives of 52 people and injured more than 700 others.
Using the #WalkTogether hashtag, the campaign is "inspired by the scenes on London's streets on 7 July 2005, when public transport closed down and thousands calmly walked home", British Future said.
The London tube network also came to a stop at 11:30am to allow passengers a minute of silence to pay respects to the victims of the attack.
Those participating have taken photos of their walks alongside other commuters.
Others have left messages of condolences and remembrance on Twitter.
Gill Hicks, a survivor of the attack, walked with religious leaders from the Muslim, Christian, and Jewish faiths, carrying a tribute sign saying "together".
"My life and those around me changed forever on July 7, 2005. I believe in the power and brilliance of humanity – my life was saved by strangers, people who never gave up, people who risked their own lives to save mine," Hicks said. "To them, I was a precious human life – my rescue wasn't dependent on my faith, my colour, my gender, or wealth."
