21 July 2005 London attempted bombings

On 21 July 2005, four attempted bomb attacks by four Islamist extremists disrupted part of London's public transport system as a follow-up attack to the 7 July 2005 London bombings two weeks earlier. The explosions occurred around midday at Shepherd's Bush, Warren Street and Oval stations on the London Underground, and on London Buses route 26 in Haggerston.
