Three people who were travelling in a light aircraft were treated by paramedics after a plane came down by the A40 between Raglan and Abergavenny.

The three are believed to have been a father and two children, a boy and a girl, who were rescued by two men who pulled them out of the wreckage, which burst into flames.

Daniel Nicholson told Sky News that he was driving home when the plane “came out of nowhere” and crashed into barriers on the busy road at about 11am.

He said he and another man helped to pull the three occupants - a father and his two children - out of the wreckage.

“The plane went down and burst into flames,” he said.

"I ran over to the plane and they were screaming but they were stuck."

Mr Nicholson, 46, from Abergavenny, said he put his foot through one of the aircraft’s windows and freed a boy and girl.

Police, fire and ambulance crews were called to the incident in Monmouthshire at around 11am after the plane was reported to have made an unscheduled landing and collided with wiring.

A spokesman for Gwent Police said their injuries were “not life-threatening”.

The Welsh Ambulance Service said they were taken to Nevill Hall Hospital in Abergavenny.

Western Power also attended the scene to help deal with the incident.

Drivers are being advised to avoid the area and use diversions on the A4042 and A472.

Traffic is queuing and the A40 remains closed in both directions from the High Street in Raglan to the Hardwick gyratory in Abergavenny.

According to traffic reports, smoke was blowing across the road.

There are hour-long delays to train services in the area.
