Wouldn't be the first time. China drops debris and rocket stages on populated areas all the time

And rocket fuel, which isn't great for pretty much anything alive.

Depends on the rocket fuel.

Methalox: Harmless gases. Methane is a greenhouse gas, but it's not toxic. Basically like a bunch of cows burping.
Kerolox: Kerosene is an oily liquid, so not great for the environment, but not highly toxic.
Hypergolics: Hydrazine derivatives and nitrogen tetroxide are both highly toxic.

The Tianlong-3 in this article uses kerolox. The Long March 2C booster which fell near a village last week uses hypergols.

Yeah, primarily hypergolics are the fun ones. I didn't hear about the booster that fell near a village recently, but there was one that I think had an emergency dump over some village or town a few years ago.
