M4 to stay shut 'for hours' westbound near Cardiff
BBC Wales Today's Caroline Evans reported from the scene at around 1830 BST
The M4 westbound near Cardiff remains closed until later on Friday evening, after a fatal crash involving a lorry and a transit van.
Motorists were facing delays of up to three hours, and the M4 westbound between Cardiff West and Pencoed remains shut until at least 2200 BST.
The lorry rolled down an embankment off the motorway, and a van was left on its side on the carriageway at 1000 BST.
One person was killed and two people were treated for minor injuries.
The Welsh Ambulance Service said one person was confirmed dead at the scene, and the two injured people were taken to the Princess of Wales Hospital, Bridgend.
The crash happened between Pencoed and Miskin
Drivers heading west along the M4 towards Bridgend are being advised to take a diversion - however, delays of up to three hours have been reported by motorists attempting to travel to the suggested diversion at junction 33.
It is suggested drivers leave the motorway at junction 33, to take the A4232 Ely link road to Culverhouse Cross, before joining the A48 westbound towards Cowbridge, and on to Bridgend.
'Plan your route'
Police had hoped the M4 junctions between 33 and 35 would reopen at about 2000 BST, but the carriageways are now likely to stay closed until about 2200 BST, as a crash investigation and recovery operation continues.
An assembly government spokesman said: "As a fatal collision, this requires closure of the westbound carriageway of the M4 while recovery operations proceed and a full police investigation is conducted."
Motorists are also being warned that the eastbound carriageways may need to be shut for a short period while the damaged vehicles are removed from the motorway.
A police spokesperson added: "We are asking motorists to plan your route in advance so that you can safely avoid the area and take alternative routes."
The incident involved a white Volvo lorry and white Ford transit van, and police have appealed for any witnesses to come forward.
