On Tuesday, London will commemorate the 10th anniversary of the July 7, 2005, bombings that killed 52 people — the worst single terrorist attack on British soil.
A service will take place in St Paul’s Cathedral to remember those who died in what became known as the 7/7 bombings, reports the BBC. Family members of the victims and some of those who were injured will attend the ceremony.
A minute’s silence will be held across London’s transport network at 11:30 a.m. BST (6:30 a.m. ET) with London Underground trains and buses coming to a halt wherever possible.
There will also be a service at Hyde Park’s July 7 Memorial.
Just after 8:30 a.m. on 7 July, four suicide bombers with links to al-Qaeda detonated homemade bombs on three subway trains and one bus during the morning rush-hour.
Twenty-six people lost their lives in the bombing at Russell Square, six died at Edgware Road and seven in the explosion at Aldgate.
About an hour later, 13 people were killed as a fourth device detonated on a double-decker bus in Tavistock Square. More than 700 people were injured in the bombings.
“Ten years on from the 7/7 London attacks, the threat from terrorism continues to be as real as it is deadly — the murder of 30 innocent Britons whilst holidaying in Tunisia is a brutal reminder of that fact,” said U.K. Prime Minister David Cameron. “But we will never be cowed by terrorism.”
