The 7 July 2005 London bombings, sometimes referred to informally as 7/7, were a series of four coordinated suicide attacks carried out by Islamist terrorists that targeted commuters travelling on London's public transport during the morning rush hour. The second bomb exploded in the second car of another six-car London Underground Circle Line train, number 216, which had just left Edgware Road and was travelling westbound towards Paddington.
