UPDATE: 8.20pm

PONTYPOOL residents have been evacuated from their homes after a car fire spread to a gas main.

Several crews from South Wales Fire and Rescue attended the blaze in Wainfelin Avenue Pontypool at around 7pm this evening.

Eyewitnesses describe being evacuated from their homes as flames spread from a car fire to an gas main and electric box, causing power outages and sparks shooting “10 feet into the air”.

Fire fighters have extinguished the two car fires and are now tackling the gas main fire.

A South Wales Fire and Rescue spokeswoman confirmed the fire involved four properties and eight residents have been evacuated.

Ian Gilbert, 37, of Wainfelin Avenue, was in his front room four doors down when he noticed people standing outside in the street.

“When I looked around I saw it was a blaze and fire engines arrived shortly after. I think they had problem accessing the road as it is quite narrow.

“As they started dousing the fire sparks started shooting up 10 feet into the air and after that they started to hose the cars.

“There are still flames about 10-feet high and the gas main is burning out as we all stand outside."
