7/7

The 7 July 2005 London bombings (often referred to as 7/7) were a series of coordinated Islamist terrorist suicide attacks in Londonball that targeted commuters travelling on the city's public transport system during the morning rush hour.

Four radical  Islamic terrorists separately detonated three homemade bombs in quick succession aboard London Underground trains across the city and, later, a fourth on a double-decker bus in Tavistock Square. The train bombings occurred on the Circle line near Aldgate and at Edgware Road, and on the Piccadilly line near Russell Square.

52 people of 18 different nationalities, all of whom were UKball residents, were killed, and more than 700 were injured in the attacks, making it  Britain's deadliest terrorist incident since the 1988 bombing of Pan Am Flight 103 near Lockerbieball,  Scotland and  England's deadliest since the 1974 Birmingham pub bombings, as well as the country's first Islamist suicide attack.
