A ceremony has been held in east London to mark the 15th anniversary of the IRA Docklands bomb.
The bomb, on 9 February 1996, killed two people and brought to an end an 18-month IRA ceasefire.
Among the speakers at the service, held in South Quay Station, was the brother of one of the dead and a woman severely injured in the 7/7 attacks.
Organisers released 12 whites doves as a "symbol of desire for peace and an end to all terrorist violence".
Inam Bashir, 29, and John Jeffries, 31, were killed and dozens of people were hurt in the attack, which shook buildings and shattered windows.
Two buildings partially collapsed.
One of the speakers at the service was Berverli Rhodes, founder of the Survivors Coalition Foundation, who was badly hurt when Islamic extremists set off four bombs on the London transport network.
A spokesman for the Docklands Victim's Association said: "This appalling act of terrorism also injured countless innocent people and, due to the inconceivable force of the explosion, completely destroyed the surrounding area.
"We also remember those who have been killed in other terrorist atrocities throughout the world."
Ishan Bashir, who lost his brother Inam in the attack, said of the day: "I try to black it out. The last conversation we had was at quarter to seven.
"He said they had been told to evacuate. It was only then one of my employees heard a bomb had been exploded.
"I came here and we were told to go looking in hospitals.
"It was only the next day we found out Inam and John lost their lives."
James McArdle, who planted the Docklands bomb, was freed in 1998 as part of the Good Friday Agreement.
