On Saturday March 20th 1993 an IRA bomb went off in Warrington killing 12 year old Tim Parry and three year old Johnathan Parry. 54 other people were injured in the blast.
It was a day in which the 'Trouble's' of Northern Ireland quite literally hit mainland Britain and Bridge Street in Warrington.
Two bombs were detonated a minute apart from each other, Johnathan Ball died at the scene. Tim suffered serious injuries and his life support machine was switched off five days later.
Tim's father Colin told us: "The whole day is razor sharp, I remember it frame by frame from the moment Tim left to the house until the moment we were told of the terrible thing that happened to him."
He continued: "I lay in his hospital bed and held him and told him I loved him and the machine was switched off. Within moments he stopped breathing. To see your son die in front of you was a numbing moment."
Following the tragedy the Parry's set up The Tim Parry and Johnathan Ball Foundation for Peace, to promote peace and non-violent conflict resolution. They charity estimates they've helped more than 25,000 people by bringing opposite groups together to try and resolve their issues.
Mr Parry said: "Since the foundation's been running a huge number of people have benefitted. It's much harder to hate someone when you've met them."
