The blasts, which shook London, have also brought a lot of agony to friends and relatives of the victims.
A week later, people are still searching hospitals desperately in hope of information about loved ones.
At the blast scenes, posters and photos of the missing can still be seen on walls and trees. The police have been unable to identify all the bodies because of the horrific nature of the injuries sustained by those who died.
