A woman and her daughter have been killed in a road collision in Co Antrim involving a quad bike and a tractor.

The incident occurred on Tuesday evening on the Whitepark Road in Ballycastle. The Causeway Coastal Road was closed for a time, but has since reopened.

The woman and the young girl were pronounced dead at the scene. A second girl was airlifted to hospital in Belfast and it is understood she is in a critical condition.

An investigation is under way and the Police Service of Northern Ireland (PSNI) has appealed for anyone who witnessed the collision or who has dashcam footage to contact them.
