A river could be posing a serious health risk to local people after it suddenly turned a blood-red colour.
Experts are baffled by the strange phenomenon, which has led people to fear the quality of the drinking water in the city of Tyumen, Russia.
Officials in western Siberia have not yet released the results of a barrage of tests on samples taken from the river, but state-owned news agency Itar-Tass has labelled the incident a “Biblical bombshell”.
Worried locals suspect the dumping of unknown chemicals into the normally murky waters of the small Molchanka River, reported The Siberian Times.
