Homes evacuated after apparent landslip
Homes have been evacuated after an apparent landslip in a former mining community.
One video on social media shows buildings deep in sludge and mud as water pours down what appears to be a street.
Another shows a white car stuck swamped among muck and rocks.
Some residents have already been evacuated to a local leisure centre, the council said.
Local resident Wayne Green said the slide settled at the bottom of the hill and wrecked parked cars and flooded properties.
He said that the fire service had told him they were leaving an engine at the bottom of the street overnight.
"If any of the residents hear a siren then we have got to evacuate and they told us which route to take,” he said.
"They're going door to door telling the residents which way to evacuate the street if there is another slip, he said.
Blaenau Gwent council said: "We are aware that a number of households in the Cwmtillery area of Abertillery have been evacuated by emergency services.
"We are making arrangements for those affected and a rest centre has been set up at Abertillery Sports Centre. We are on site with partners assessing the situation."
South Wales Fire and Rescue Service confirmed they have two fire engines at the scene but did not give any more detail.
Natural Resources Wales and the Coal Authority have been contacted for comment.
