A Belfast family has escaped injury after a pipe bomb was thrown at their home.
The device was thrown through the front living room window of the house in the nationalist New Lodge area of north Belfast shortly after midnight.
Two adults and three children, who were in the house at the time of the attack were not harmed, but the bomb started a fire which caused extensive damage.
The RUC was investigating the attack, which came hours after a stash of pipe bomb parts were seized by police at a "manufacturing base" in a town blighted by recent sectarian attacks.
Component parts for 11 pipe bombs were uncovered last night following a planned search of derelict houses in Larne, Co Antrim.
A balaclava, surgical gloves and the remains of a number of fireworks were also found at the rear of a garden in the Fairway area of the predominantly Protestant Antiville estate. No arrests were made.
There have been more than 30 pipe bombings in Northern Ireland so far this year in what is being regarded as a sectarian campaign mostly waged against Catholics.
Although Larne has been one of the areas which has suffered most, similar attacks have occurred in towns across Co Antrim and Co Derry.
