The 20th anniversary of the July 7, 2005, attacks on London's transit system by Islamic extremists that killed 52 people and injured more than 700 was remembered with ceremonies and the laying of flowers across the city.

King Charles III is leading commemorations marking 20 years since the 2005 London transit bombings, the deadliest attack on the city since World War II.

On 7 July 2005, four British Muslim suicide bombers blew themselves up in central London while on board three subway trains and a bus. They killed 52 people and themselves and injured around 700 people.
