The RUC is investigating a number of death threats purporting to come from the "Real IRA" which have been made against prominent loyalists in the Lurgan and Portadown areas.
Among those threatened is a leading loyalist, Mark Fulton, currently serving a four-year prison sentence in Maghaberry prison.
Last night a loyalist source in mid-Ulster said that a number of people had been told to leave Northern Ireland by midnight on Friday or be shot.
