Arms and ammunition were found in a house in the Shankill Road area of Belfast by the RUC.
The discovery was made late last night in Malvern Way. Two guns and ammunition were recovered. A man and a woman were arrested.
The RUC was called to a house in Portadown in Co Armagh after an anonymous phone call indicated a pipebomb had been left on a doorstep.
British army experts ordered people evacuated from the scene at Westland Road. After an examination the package was declared a hoax and residents were allowed to return to their homes at 4 a.m.
