Protocol on Incendiary Weapons

The Protocol on Prohibitions or Restrictions on the use of Incendiary Weapons is a United Nations treaty that restricts the use of incendiary weapons. It is Protocol III to the 1980 Convention on Certain Conventional Weapons Which May Be Deemed To Be Excessively Injurious Or To Have Indiscriminate Effects. Concluded in 1981, it entered into force on 2 December 1983. , it had been ratified by 126 state parties.

Incendiary weapons as a category does not appear to include thermobaric weapons, and international law does not appear to prohibit the use of thermobaric munitions against military targets. Their use against civilian populations or infrastructure may be banned by this Protocol. , all past attempts to regulate or restrict thermobaric weapons have failed.

Content
The protocol prohibits, in all circumstances, making the civilian population as such, individual civilians or civilian objects, the object of attack by any weapon or munition which is primarily designed to set fire to objects or to cause burn injury to persons through the action of flame, heat or a combination thereof, produced by a chemical reaction of a substance delivered on the target. The protocol also prohibits the use of air-delivered incendiary weapons against military targets within a concentration of civilians, and limits the use of incendiary weapons delivered by other means. Forest and other plants may not be a target unless they are used to conceal combatants or other military objectives.

The protocol lists certain munition types like smoke shells which only have a secondary or additional incendiary effect; these munition types are not considered to be incendiary weapons.

Review of doctrine
An investigation into the doctrine taught by various militaries was conducted sometime after 2001 by the International Committee of the Red Cross as part of its database on Customary International Humanitarian Law. Rule 84 deals with this Protocol.
