Nothing wrong with using it as smoke or a mark or against troops or equipment. Not ok against civilians but Russia clearly doesn't give a crap about that.
For a good discussion of the legalities of WP weapons, check out
this article from 2019, when Turkey was reported to have used WP against Kurdish rebels.
Legally, WP is neither an incendiary weapon (designed with the primary intent to start fires and/or burn people and things) nor a chemical weapon.
The Law of Armed Conflict does not outright ban the use of incendiary weapons, even if WP were so classified. Incendiaries can be used, subject to the following rules:
Quote:
Article 2, titled "Protection of civilians and civilian objects," prohibits four uses of incendiary weapons:
- Making civilian or civilian objects the object of attack by incendiary weapons.
- Attacking a military objective located within a concentration of civilians with air-delivered incendiary weapons.
- Attacking a military objective located within a concentration of civilians with a non-air-delivered incendiary weapon, except when such military objective is clearly separated from the concentration of civilians and all feasible precautions are taken to minimize collateral damage.
- Making forests or other kinds of plant cover the object of attack by incendiary weapons except when such natural elements are used to cover, conceal or camouflage combatants or other military objectives.
The use of WP as a weapon goes back at least as far as WWII. See

his one of aerial WP munitions being used against a flight of B-24s.
