Russian officials are investigating after disturbing images of a river that had turned blood red had surfaced on social media.
On Wednesday, The Siberian Times reported that the Daldykan River, near Norilsk in the Kransnoyarsk region, about 4,300 northwest of Moscow, turned the deep red colour possibly due to runoff from a nearby factory.
The Nadezhdinsky factory, owned by Norilsk Nickel, is a metalluric plant which processes nickel concentrate. The company disputes any claims that they discharged any industrial waste into the river. However, a spokesperson said on Wednesday that the company would continue to monitor the situation.
The company also provided images of the river that seemed to be normal in colour to a news agency. However, the exact location of the photos is unknown.
