Sinn Fein President Gerry Adams has revealed he was warned by police of another threat to his life.
Gerry Adams said his party would not be deflected by threats
The party said members would "take precautions to minimise risks" but would continue to do the work they "were elected to do".
Earlier this month, Mr Adams said dissident republicans were behind threats to him and other party members.
Republican sources said Mr Adams, Martin McGuinness and Gerry Kelly have all now increased their security.
Police have warned recently about the possibility of attacks by dissident republicans to try to derail efforts to restore the Northern Ireland devolution.
