A town will come together on Saturday ahead of the 20th anniversary of an IRA bomb attack which killed two young boys.
The Warrington bombing, on March 20 1993, tore through the Cheshire town's shopping centre and instantly killed three-year-old Johnathan Ball. Tim Parry, 12, became the second victim when he died of his injuries five days later.
A further 56 people were injured by the two bombs, which were placed in litter bins and exploded shortly after midday that Saturday afternoon.
No warning was given and nobody has ever been prosecuted for the outrage, which took place the day before Mothering Sunday.
In the aftermath of the atrocity there was a wave of public outcry in the UK and in Dublin, where a book of condolence was opened at the General Post Office.
Tim's parents Colin and Wendy set up the Tim Parry Johnathan Ball Foundation for Peace which has since become an internationally recognised centre for conflict resolution and victim support.
The couple will join survivors, civic leaders and the local community at a commemorative event on Bridge Street, where the bombs struck, tomorrow.
Johnathan's family will be represented by relatives of his parents. His father, Wilf, died in 2004 and his mother, Marie Comerford, died in 2009.
The ceremony will include speeches from dignitaries and community representatives, choir performances, readings and a minute silence.
The anniversary will also be marked by an exhibition at Warrington Museum reflecting the shock suffered by the community and how people re-built their lives.
