On Thursday morning, a river in eastern China suddenly turned a bloody shade of red, according to unverified reports by ABC News, China News, Shanghaist, and others.
"Local residents say the river was running normally at 4am, but it started to redden at around 6am, and in no time turned as crimson as blood,"China Radio International reported.
Here are some incredible pictures that appear to show the crimson river.

While nobody is quite sure what caused the alarming change, the ABC report said "a paper manufacturer, a food-coloring company and a clothing-maker" were located along the river. When China's Jian River turned red in 2011, it was traced to a company that was illegally dumping red dye into the waterway. The Yangtze River had a similar incident, back in 2012, which was thought to have been caused by silt in the river.
ABC News notes that the Wenzhou Environmental Protection Bureau is investigating.
