Just in case anyone isn’t familiar with white phosphorus it is one of the most vile materials known to humans and unfortunately easily accessible to monstrous people without a conscious to use against civilians in genocide. They use air bursts to spread it over as wide an area as possible & prevent first responders from accessing injured people. It’s extremely poisonous to inhale fumes or touch, and it’s sticky to human skin and clothing and most other materials. When exposed to the atmosphere it ignites, even shortly after being submerged in water.
