The legality of incendiary weapons, specifically those designed to project burning streams of flammable liquid, is a complex issue in international law. While not subject to a complete, outright ban, their use is significantly restricted under Protocol III of the Convention on Certain Conventional Weapons (CCW). This protocol prohibits their use against civilian populations and restricts their use against military targets located within concentrations of civilians. Furthermore, using such weapons against forests or other kinds of plant cover is prohibited unless they are used to cover, conceal, or camouflage combatants, or are themselves military objectives.
The restrictions on these weapons stem from the horrific injuries they can inflict, including severe burns, respiratory damage, and psychological trauma. Historically, their use has resulted in significant suffering and indiscriminate destruction. The regulations aim to balance military necessity with humanitarian concerns, acknowledging the potential for widespread and indiscriminate harm. Understanding these legal and ethical implications is crucial for any discussion surrounding the role of incendiary weapons in modern warfare.
