The trade union movement is planning a public event this week to let people express their outrage at the Massereene murders.
The details are likely to be finalised today, and are expected to include a public gathering in Belfast city centre at lunchtime on Wednesday.
In a statement yesterday, the Northern Ireland Committee of the Irish Congress of Trade Unions called on all workers to show their disgust at the murder of the two soldiers.
Peter Bunting, assistant general secretary of the ICTU, said: “There is a line which is fine but deep and it separates peace and violence, truth and lies, justice and murder, and civilisation and barbarism.
“The perpetrators of last night’s barbaric act are firmly on the wrong side of that line. All working people must unite to condemn and isolate those whose first resort is indiscriminate savagery.
“The two victims of last night’s murders were servants of the public, as were the pizza delivery people cruelly injured in the attack. Our thoughts are with all of their families on this day.”
