A 67-year-old woman and a 19-year-old man have died in a road crash in Co Down.
Police said two cars collided on the old Dublin Road south of Newry.
The 19-year-old driver of one of the cars was pronounced dead at the scene.
The woman passenger of the other car was taken to hospital, where she later died of her injuries.
It is understood she was originally from Drogheda in Co Louth.
The deaths bring to four the number of people killed on the roads in Northern Ireland in the past 24 hours.
