A vigil will be held in Morpeth on Saturday following the atrocity in Manchester on Monday night.
Twenty-two people were killed and more than 60 people were injured after a man set off a bomb in the foyer at Manchester Arena.
Morpeth Mayor Nic Best will be among those present at the vigil, which will take place at The Amnesty Peace Garden next to The Chantry from 6pm.
Northumberland County Council has opened a book of condolence following the attack. It is available to sign at the reception area in County Hall, Morpeth.
County council deputy chief executive Daljit Lally said: “The events in Manchester were truly shocking and I am sure I speak on behalf of everyone in Northumberland in sending our condolences to all those affected by these terrible events.
“We stand together with Manchester, the victims and their families. Terrorism will not win.”
