A murder investigation is now underway with the PSNI, with detectives 'working at pace to determine the circumstances.'

The woman and one of the children were pronounced dead at the scene, while the man and the other child were taken to hospital.

The man was taken by air ambulance to the Royal Victoria Hospital, Belfast, and the child by ambulance to South West Acute Hospital.

While PSNI enquiries are at an early stage, he has asked for 'patience as we work to understand the events that have taken place.'

Additionally, the PSNI appealed for anyone with information, CCTV, or dashcam footage to contact them.
