The pictures were taken at the Caspian Riviera in the city of Aktau in southeastern Kazakhstan, with bright red spots visible in the snow. 

These incredible photos show a stretch of coastline turning dark red - like large blood streaks. Bright red spots can be spotted on white snow, creating a strange phenomenon. 

Local environmental experts claim that the water is not polluted despite its disturbing appearance. According to local media, the reason for its color change is a special type of algae called Diatoms.

Despite its appearance, algae do not pose a danger to fish or people exposed to it. If the water is polluted, it will have an extra layer of sparkle, according to the report.

Despite the official statement, internet users are still disturbed by the strange appearance of the sea.

One said: I think it looks like a sign of nature signaling people. Many other comments also agree with this statement.
