A Splinter group has issued death threats to the widow and son of veteran republican Martin Meehan who died of a heart attack a fortnight ago.
Briege and Martin Og Meehan are among 16 republicans who received threats from a group calling itself the Irish Republican Liberation Army.
Sinn Féin MLA Gerry Kelly said yesterday (Friday) the threats would not stop any republican from working for political and social progress.
"These threats are coming from people who claim to be republicans," the north Belfast assembly member said.
"These people have nothing constructive to offer the republican struggle.
"They have nothing like a fraction of the committed activism of people like Martin and Briege Meehan and the many other republicans being threatened."
Four members of the Orange Order were yesterday also warned that they were under threat from dissident republicans.
The Orange Order said members of the institution had been advised to be on their guard and they were also warned anti-agreement republicans were planning an attack on the caretaker of an Orange Hall in Antrim.
"We believe that dissident republicans have been responsible for recent attacks on Orange Halls in Armagh and Tyrone," the organisation's grand secretary, Drew Nelson, said.
The latest threats were condemned by Northern Ireland Policing Board chairman Sir Desmond Rea.
"On behalf of the Policing Board, I unreservedly condemn these threats against people who have chosen to step forward and serve the community," he said.
A Sinn Féin assembly member has claimed police are to set up a mobile station in the Co Antrim village of Stoneyford from next week following claims that loyalists were intimidating Catholic residents.
Paul Butler met Assistant Chief Constable Duncan McCausland and District Commander Paula Hilman yesterday to voice his concerns about the alleged intimidation, which he claimed is being orchestrated by a "well-known loyalist".
