One woman has died and another is in critical condition after a two-vehicle collision in Ballymena.
The collision happened on the A26 Crankill Road just before 6.45pm.
The PSNI said the 37-year-old woman was the front seat passenger in a red Toyota Yaris that collided with a black Passat on Friday evening.
The driver of the Yaris is in a critical condition while two rear passengers sustained injuries that are not thought to be life threatening at present.
Two male occupants of the Passat were taken to hospital but have since been treated and released.
Inspector Marc Riddell appealed for witnesses to the collision to get in touch: “I would like to hear from anyone who saw either vehicle on the Crankill Road prior to the time of the crash, or anyone who may have witnessed the collision or captured dashcam footage of it. Officers can be contacted by calling 101, quoting reference 1558 21/06/19.”
A Northern Ireland Ambulance Service spokesperson said: "NIAS dispatched two rapid response paramedics, four emergency crews and one ambulance officer to the scene.
"The charity air ambulance was also dispatched to the incident with a HEMS team on board. Following initial treatment at the scene, three people were taken to Belfast Royal Victoria Hospital by land ambulance."
The A26 was closed at the M2 Junction 12 just outside Ballymena for a time overnight while police investigated the crash.
