It's three years since four suicide bombers struck in central London.

Fifty two people were killed and more than 770 injured.

Among those who died was Kent schoolboy Philip Russell, who was a victim of the Tavistock square bombing.

His parents will be among those laying flowers in remembrance today.

His father Graham, from East Peckham, says it helps to be among the relatives of those killed.

The co-ordinated attacks hit the transport system as the morning rush hour drew to a close.

Three bombs went off at around 8.50am on underground trains near Liverpool Street and Edgware Road stations, and on another between King's Cross and Russell Square.

The final explosion was around an hour later on a double-decker bus in Tavistock Square.

Beverli Rhodes, from Ashford, was on the tube under Russell Square when the bomb went off.

It left her with horrific head and facial injuries.

She said:"I am totally different person from the person who took that train in the morning.

"I do see things very differently. I don't have the same outlook on life at all."
