A toddler has died and a woman and an infant have been seriously injured in a stabbing in County Antrim.
The alert was raised on Monday morning at an isolated house at Bankhall Road, Magheramorne, near Larne.
It is understood the injured woman is the mother of the children.
The incident is being treated as domestic. Neighbours reported hearing a police helicopter at about 10.30 GMT and emergency services were called to the scene.
The house has been cordoned off as a police operation continues.
Police have released few details, only confirming officers and emergency services were dealing with an “incident”.
Gordon Lyons, a DUP assembly member from the area, said it was clear “something horrific” had happened.
“It is absolutely awful when you hear of anybody suffering in this kind of way but when young children are involved it is particularly horrific,” he said.
“My thoughts and prayers and the thoughts and prayers of everybody across east Antrim will be with the family.”
