London remembers the terrorist attack on the tube that killed 52 people on this day 10 years ago

Ten years after the terrorist attacks that killed 52 commuters and injured 700 others in London, the city’s residents are remembering the victims and reflecting on a day that turned Londoners’ morning commute into a nightmare.

“I could hear screaming and I could smell smoke and I remember reaching out to try to stand up and I couldn’t actually move. I was stuck in the chair and then everything just went black…When I woke up, I remember it was just—the carriage was full of smoke—completely dark—and it was just chaos everywhere, really,” survivor Cynthia Chetty told The Independent.

The bombings, in which four al-Qaeda-related suicide bombers attacked three tube stations and a bus, left the country in a state of shock—it was the worst terrorist attack England has ever seen.

This morning, Prime Minister David Cameron and London Mayor Boris Johnson layed wreaths at a memorial in Hyde Park, where Prince William also later arrived to pay tribute, the BBC reports.
