A bomb has been found in a hijacked car left outside Antrim Road police station in north Belfast.
A number of controlled explosions were carried out
It was found after a six-hour operation involving several controlled explosions which damaged a number of properties.
No-one was injured, as residents had been moved to safety. Police said the car had been hijacked on Thursday evening. The area has since reopened.
Meanwhile, more than 700 pupils at St Colm's High School, Twinbrook, were sent home following a security alert.
The alert began at 0930 GMT on Friday when a pipe with wires on it was discovered close to the front gates.
School principal at St Colm's High, Imelda Jordan, commended staff and pupils for their swift response and condemned those responsible.
"The children's parents sent them to school today believing they would be in our care and kept safe throughout the school day, I wasn't able to do that," she said.
"I had to send 700 children home without transport and without being able to contact their parents."
A pipe with wires protruding was left at the gates of the school
The device was later declared an elaborate hoax.
Local assembly members described those responsible as despicable.
Near Londonderry, a couple and their 10-year-old daughter have escaped injury in a blast bomb attack at their home.
The attack happened at Benview Estate in Coshquin shortly after midnight.
Jimmy Poole who was in the house with his family at the time said it was a personal dispute with loyalists.
He said the attack was not political.
"They are all cowards. They won't come to your face. They come behind your back and do it. They won't come straight to your door," he said.
Sinn Fein condemned the attack. The party said loyalism needed to move away from violence.
"Our party's reaction is shock," said Councillor Billy Page.
"This is a very close knit community, a mixed community and a very elderly community around them. We totally condemn it."
The Poole family said they would not be intimidated out of their home.
Police investigating the attack said no motive had been established.
They have appealed for information.
