A town will fall silent today to mark the 20th anniversary of the murder of two boys in an IRA outrage.
Tim Parry, 12, and three-year-old Johnathan Ball were killed when two bombs exploded in litter bins in Warrington, Cheshire, on March 20, 1993.
A further 56 people were injured in the attack on Bridge Street in the town centre.
No warning was given and nobody has ever been prosecuted for the outrage, which took place the day before Mothering Sunday.
A minute silence will be observed throughout Warrington at 12.27pm today, the exact time of the bombing.
It follows a civic service of remembrance which took place in Bridge Street on Saturday.
Cllr Mike Hannon, deputy leader of Warrington Council, said: "Today is the anniversary and we believe it is important to reach out and to take time out of our busy lives on this important day to remember, reflect and support each other."
The anniversary is also being marked today at the Tim Parry Johnathan Ball Foundation for Peace, which was set up by Tim's parents, Colin and Wendy, in the aftermath of the tragedy.
The charity is hosting a conference entitled The Cost of Peace and the Price of Extremism.
Mr Parry will be among the speakers, who also include Baroness Newlove, the widow of murdered Garry Newlove who now campaigns for victims' rights, and Graham Foulkes, whose son David died in the July 7, 2005 bombings in London.
