A serious collision has led to the M1 motorway being closed.
The closure is in place between Junctions 14 and 15, near the Tamnamore roundabout.
Emergency services are on the scene.
Police have described the collision as “serious”.
Vehicles are being turned back from the scene and the motorway is being closed completely.
It is understood two vehicles have been involved.
And, according to the Northern Ireland Ambulance Services, it has despatched three crews and a rapid response unit to the scene. Two doctors – as well as the hazardous response team – are attending too.
An eyewitness said it was an “awful sight” and there was “debris everywhere”.
Police say the M1 is likely to be closed for a significant length of time.
There are no further details at present.
