A number of nationalists in Coleraine have been told they are under threat from loyalist paramilitaries.
Billy Leonard said the community must stand together
It is understood the men were informed by the police on Friday afternoon.
Local Sinn Fein Councillor Billy Leonard said the whole community, nationalist and unionist, must stand together against the threats.
"It's got to be a case of unionist and loyalist politicians standing up and being proactive about what is emanating from their community," he said.
"It's got to be much more than condemnation," Mr Leonard added.
However, the DUP mayor of the town denied that loyalist politicians are not doing enough to promote community relations.
Timothy Deans said he has worked closely with the police and community representatives to improve community relations.
"I would just say step back look at the wider picture and realise this does not achieve anything," Mr Deans said.
