Police say they believe Hasib Hussain, 18, detonated a device on a bus at London's Tavistock Square.

British Police release a security camera photo of a suspect in the London bombings as he headed through a train station, less than an hour and a half before the double-decker bus he was riding blew up.
Police said 18-year-old Hasib Hussain of Leeds boarded the Number 30 bus that blew up near Tavistock Square, killing 13 people including Hussain himself. They also say three other men he traveled with that morning were responsible for the subway bombings that morning. All apparently died in the attacks. The question of why Hussain boarded a bus while the others got on subway trains has intrigued police since the beginning.
The death toll from the bombings continues to climb. A man injured in the attacks died in the hospital, bringing the total fatalities to 54. Authorities say it is likely to climb higher.
