Three people have died and others have been seriously injured after a coach overturned when it collided with a tree on an embankment. It happened just before midnight on the northbound carriageway of the A3 near Hindhead in Surrey.
No other vehicles are thought to have been involved - although Police say investigations are continuing. The Hindhead Tunnel is closed in both directions between the A287 and the A283.
Three people aboard the 51-seat coach were declared dead at the scene and a fourth passenger was airlifted to Southampton General Hospital with life-changing injuries. Other passengers have been taken to hospitals in Guildford, Chertsey, Tooting, London, and Portsmouth.
The road was closed in both directions shortly after the incident. Passengers are being taken to a rest centre which has been set up nearby by Waverley Council.
The road is expected to remain closed for the several hours and diversions are in place. Motorists are asked to avoid the area until the road can be reopened.
