A PEDESTRIAN was in a critical condition in hospital on Sunday night after being hit by a car close to Belfast International Airport.
The victim, a man in his 20s, was walking along the Ballyrobin Road when he was knocked down at around 4.50pm on Saturday close to the Ballyrobin Guest House.
It is understood he suffered a serious head injury and is being treated in the Royal Victoria Hospital.
The Ballyrobin Road was closed following the accident with diversions in place.
Passengers for the airport were being advised to leave extra time for their journey.
A police spokesman said: "It is with reluctance that we close any road however, following any serious road traffic collision police have an obligation to carry out a full and thorough investigation into the exact circumstances of the collision and the scene must be closed in order for that investigation to take place."
Police have appealed for anyone with information to contact officers on 101.
Meanwhile, a young woman has died and another is seriously injured after apparently falling from a moving van about two miles outside Moycullen in Co Galway in the early hours of Sunday.
The women, both aged in their early 20s, fell from the vehicle as it was making its way past the Barna Road and Moycullen Road junction at around 2.30am.
Emergency services found the two women lying seriously injured on the roadside.
They were given medical treatment at the scene before being taken to University Hospital Galway.
One of the women was later pronounced dead, while the second woman remains seriously ill in hospital where her condition is described as stable.
It is believed the van they were travelling in was not involved in a collision and no arrests have been made.
Gardaí said their investigations into the "unusual" incident are ongoing and have appealed for information.
The deaths come as memorial services took place across the Republic to mark World Day of Remembrance for Road Traffic Victims.
Almost 40,000 people have been killed - an average of 600 a year - on roads across the island of Ireland since record-keeping began.
Almost 24,000 people have died on roads in the Republic since records began in 1959.
Statistics published last week also show that in the north, 14,839 people have died in road collisions since records were first kept in 1931.
