The incident appears to involve a blue van and a white car - possibly a BMW - at the Aller Cross roundabout on the A361 near South Molton. The incident is on the Tiverton-bound carriageway on the Barnstaple side of the roundabout. Theres very slow traffic in the area, due to one lane being closed. At 6.55pm, it was reported that the lane remains closed. Police and ambulance are at the scene, and its understood that casualties are being treated. Police are directing traffic around the roundabout, so there are long tailbacks either side. Recovery work continues.
