A West Wales river ran white after a milk tanker crashed and spilt its contents.

The dairy-filled lorry left the A482 near Llanwrda in Carmarthenshire on Wednesday evening and ended up in the River Dulais.

Natural Resources Wales said an "unknown quantity" of milk leaked from the tanker, which caused "significant discolouration".

Officers who attended on Wednesday evening after the crash, returned to the site this morning to continue to assess the impact of the spill.

And footage on social media also showed milky white water cascading over a small waterfall.

A spokesperson said: "We responded to a road traffic collision along the River Dulais, Llanwrda, Carmarthenshire that involved a milk tanker which had left the road and entered the river.

"The tanker was carrying milk and an unknown quantity has escaped and entered the river.

"This has led to significant discolouration along the river and NRW officers have been on site to assess the impact and will continue in the morning."
