A man has suffered serious injuries after an explosion in a house in Monmouthshire.

Gwent Police said homes had been evacuated following the incident on Lower Church Street, Chepstow.

South Wales Fire and Rescue Service said it had sent a large number of resources to a property after being called just before 18:30 BST on Monday.

Gwent Police said the man, who was inside the house, was taken to Morriston Hospital in Swansea.

The Welsh Ambulance Service said an air ambulance, two rapid response vehicles, an emergency ambulance and the hazardous area response team - a group of paramedics trained to go into the "hot zone" of incidents - had also been sent to the scene.

A cordon is in place, with police advising people to stay away from the area.

Smoke could be seen rising from the area

Footage, filmed from Tutshill Cliff, showed fire engines either side of the house spraying jets of water on the building to try and put the fire out.

Ben Powell lives opposite and was wearing headphones when he heard "a massive bang".

"It shook my flat," said the 27-year-old chef.

"I looked out my window and there were literally bits of the house opposite everywhere and people were screaming.

"The house looked like a bomb had gone off inside but then there was a little flame - and within two minutes the whole house had caught fire.

"It's dreadful. I just hope everyone is OK."

Wales and West Utilities said it attended the house following the explosion and was working with the emergency services to make the area safe and to investigate the cause.
