Parts of the Yellow River in China are turning red:

A half-mile section of China's Yellow River turned "red and smelly" after an unknown discharge was poured into it from a sewage pipe, state media said Monday.

The incident in Lanzhou, a city of 2 million people in western Gansu province, follows a string of industrial accidents that have poisoned major rivers in China over the last year, forcing several cities to shut down their water systems.

Upon seeing the river this morning, millions of Chinese people were on the lookout for frogs, fleas, pestilence, boils, and locusts.
