A section of the Yangtze River in Chongqing, China, has turned bright red. The cause is still being investigated, but officials say it may have been caused by recent floods stirring up silt upstream. The Environmental Protection Bureau is also looking into potential industrial pollution or sewage breaches.

Revelation 16:5 Then I heard the angel in charge of the waters say:
“You are just, O Holy One, who are and who were, in passing this sentence.

6 For they have shed the blood of the holy ones and the prophets, and you
have given them blood to drink; it is what they deserve.”
