An amazing piece of art has appeared in Port Talbot - and people think anonymous street artist Banksy could be behind it.

UPDATE: The artwork has now been confirmed as a Banksy, by the artist himself.

The artwork has appeared in the Taibach area on the back of a garage.

The image shows a child with open arms playing in what appears to be snow, but the other side of the wall reveals it is ash from a rubbish bin on fire.

Residents have taken to social media to praise the artwork and suggest it's the work of world-famous Banksy.

The artwork is believed to have appeared on the wall on Tuesday morning.

One social media user wrote: "potential banksy in Port Talbot!".

The graffiti comes after black dust from the town's steelworks covered people's houses, cars and pets in July.

People from Margam and Taibach, close to the Tata steelworks, complained the dust has left their homes filthy.

In May, the World Heath Organisation apologised after admitting figures it published which identified Port Talbot as the most polluted town in the UK were wrong.

How dangerous is the air where you live?

The global body has said it made an “oversight” in data which suggested that Port Talbot had more air pollution than the UK’s biggest cities.

A WHO database was published which suggested the south Wales town had a fine pollution level of 18 micrograms of M2.5 pollution particles per cubic metre of air.

This compared to 14 micrograms in London and 13 in Manchester - all above a national guideline of 10 micrograms.

But the figure has since been described as “erroneous” by WHO director Dr Maria Neria after being challenged by Neath Port Talbot council.

In a letter addressed to the council, Dr Neria said the air pollution level for Port Talbot was instead measured at 9.6853 micrograms - just under half of the figure originally given and below WHO air pollution guidelines.
