A woman and her two children have escaped injury in a pipe bomb attack in County Antrim.
It is the second time the house has been attacked
The device was thrown at a house in the Dunvale area of Ballymena at about 0130 GMT on Monday.
The woman and her 22-year-old son and daughter, 17, were in the house. It is the second time the house has been attacked within the past five weeks.
The blast caused substantial damage to the front of the house and to the ceiling of a front room.
Police said they were trying to establish a motive.
Bomb disposal experts were called to the scene.
In September, there was a petrol bomb attack on the house.
Detectives have appealed to anyone with information to contact them at 0845 600 8000 or by calling Crimestoppers 0800 555111.
Ulster Unionist councillor Neill Armstrong said he condemned the attack.
"It is an absolute disgrace and I would make an appeal for anyone who actually saw what happened to please go to the police," he said.
"It is the only way that we can get these people off the roads and the streets."
Police are investigating how the fire started
SDLP councillor Declan O'Loan said there was no doubt "this attack had the capacity to kill".
"There can be no excuse or justification for it. Whilst at this point in time the police have not declared a motive for the attack, the use of a pipe bomb points in the direction of loyalist paramilitaries."
In a separate incident in the town, a fire which badly damaged a house in the Lantara estate is being treated as suspicious.
It was reported to police at about 0100 GMT on Monday.
No-one was in the house at the time but a number of neighbouring homes had to be evacuated for a short time.
Police are investigating how the fire started and have appealed for witnesses to contact them.
