On July 7 suicide bombers on three London Tube trains and a bus killed at least 56 people. Most of the victims were under the age of 30 and on their way to work.
Mother-of-two Susan Levy, 53, from Cuffley, Hertfordshire, was injured in the Russell Square Tube blast minutes after saying goodbye to her youngest son, Jamie, 23. The two took a commuter rail line into London, but parted at Finsbury Park for her to take a Piccadilly Line train. She died later in hospital.
