The Azov Sea Turned Bloody Red

Scientists and citizens are baffled as the waters of the Azov Sea turned bloody red close to Berdyansk village. "It might be a sign of the coming events" say the locals, though the officials try to calm people down claiming that this is perfectly normal even that it doesn't happen often can be explained by the natural reasons. However it is still unclear what happened, as it might have different causes and the ones as ugly as toxic pollution are not excluded from the list.
