Four suicide bombers struck in central London on Thursday 7 July, killing 52 people and injuring more than 770.
The co-ordinated attacks hit the transport system as the morning rush hour drew to a close.
Three bombs went off at or around 0850 BST on underground trains just outside Liverpool Street and Edgware Road stations, and on another travelling between King's Cross and Russell Square.
The final explosion was around an hour later on a double-decker bus in Tavistock Square, not far from King's Cross.
