>>10607032 (PB) - multiple incendiary were found in the vicinity of the fires… Warfare?
Incendiary weapons, incendiary devices, incendiary munitions, or incendiary bombs are weapons designed to start fires or destroy sensitive equipment using fire (and sometimes used as anti-personnel weaponry), that use materials such as napalm, thermite, magnesium powder, chlorine trifluoride, or white phosphorus. Though colloquially often known as bombs, they are not explosives but in fact are designed to slow the process of chemical reactions and use ignition rather than detonation to start or maintain the reaction. Napalm for example, is petroleum especially thickened with certain chemicals into a 'gel' to slow, but not stop, combustion, releasing energy over a longer time than an explosive device. In the case of napalm, the gel adheres to surfaces and resists suppression.
Incendiary weapons and laws of warfare
Signatory states are bound by Protocol III of the UN Convention on Conventional Weapons which governs the use of incendiary weapons:
prohibits the use of incendiary weapons against civilians (effectively a reaffirmation of the general prohibition on attacks against civilians in Additional Protocol I to the Geneva Conventions)
prohibits the use of air-delivered incendiary weapons against military targets located within concentrations of civilians and loosely regulates the use of other types of incendiary weapons in such circumstances.[18]
Protocol III states though that incendiary weapons do not include:
Munitions which may have incidental incendiary effects, such as illuminates, tracers, smoke or signaling systems;
Munitions designed to combine penetration, blast or fragmentation effects with an additional incendiary effect, such as armor-piercing projectiles, fragmentation shells, explosive bombs and similar combined-effects munitions in which the incendiary effect is not specifically designed to cause burn injury to persons, but to be used against military objectives, such as armoured vehicles, aircraft and installations or facilities.
