Pic: River in Russia turns blood red
A river in Russia has turned blood red over the last few days, a phenomenon that locals are blaming on a nearby factory.
The Daldykan River became famous this week after an Instagram post showed it flowing blood red.
The river is near the city of Norilsk, an industrial hub north of the Arctic Circle in Siberia.
And it is one of the many factories in the area, in this case a local nickel factory, that is being blamed for the bizarre discolouration.
It is suggested that a leak in the plant's waste pipes caused the colour change, but as yet no-one is sure what type of pollutant could cause such a dramatic change to the water.
According to National Geographic, locals have seen the river turn blood red before but as it stands local officials are still investigating the cause of the discolouration.
