Protocol III to the Convention on Conventional Weapons (CCW) has failed adequately to address the serious and ongoing harm of incendiary weapons.Although 109 states have joined theProtocol on Prohibitions or Restrictions on the Use of Incendiary Weapons, incendiary weapons have continued to be used at great human cost in conflicts from Africa to Asia, Latin America, and the Middle East. Incendiary weapons cause particularly cruel injuries to human beings—civilians and combatants alike. Furthermore, incendiary weapons are prone to being indiscriminate, starting fires and causing casualties over a large area without distinguishing between soldiers and civilians.
Human Rights Watch and the Harvard Law School International Human Rights Clinic call upon states parties to Protocol III to revisit the text of the protocol and to amend its 30-year-old provisions to address more comprehensively the problems of incendiary weapons. At the CCW Review Conference in November 2011, states parties should agree upon a mandate to review and amend Protocol III, with a view to adopting amendments by the end of 2012.
At the close of the diplomatic conference that produced the CCW in 1980, states expressed hope that the new protocol would be a step toward reducing the harm of incendiary weapons.Many states also voiced disappointment with the weakness of Protocol III, however, especially its failure to prohibit all use of incendiary weaponsand its lack of adequate protections for combatants.A number of states recommended turning to the CCW review mechanism to improve the protocol,but that did not occur. The First Review Conference was not held for 15 years, and when it did take place, discussions centered on antipersonnel mines. The next review conferences in 2001 and 2006 focused on explosive remnants of war, anti-vehicle mines, and cluster munitions. With the Fourth Review Conference approaching in November 2011, states parties should seize the opportunity to reopen Protocol III in order to address the deficiencies that have hindered its effectiveness over the past three decades.
After describing the need for stronger restrictions, this memorandum lays out a series of possible amendments that would increase Protocol III’s effectiveness. First, states parties should amend the overly narrow, design-based definition of “incendiary weapon” in order to ensure that the protocol covers the most problematic modern incendiary munitions, such as those using white phosphorus. Second, states parties should bolster the protocol’s restrictions on the use of incendiary weapons. A complete ban would have the most humanitarian benefits. Alternatively, states could amend the protocol to prohibit all use of incendiary weapons in civilian areas and to require additional precautions in cases where they are used elsewhere. A prohibition on the use of incendiary weapons as antipersonnel weapons, even if they are targeted at military personnel, should also be considered.
II. The Need for Stronger Restrictions on Incendiary Weapons
Both the hazards of this type of munition and the objectives of existing law call for strengthening Protocol III. Incendiary munitions, which this paper uses as a more encompassing term than the protocol’s narrow “incendiary weapon,” cause unacceptable suffering through cruel injuries and indiscriminate effects. At the same time, the CCW seeks to prevent exactly those types of harm. The existence of Protocol III shows that states parties recognized that the two-pronged harm of incendiary munitions was inconsistent with the objectives of the CCW. The protocol itself, however, provides inadequate protections, and the time has come to remedy its shortcomings.
Incendiary munitions containing chemicals such as napalm and white phosphorus cause conscience-shocking injuries.Initial injuries include thermal and chemical burns, respiratory damage, circulatory shock, asphyxiation, and carbon monoxide poisoning, often leading to a slow and painful death. Victims who survive may suffer long term from intense pain, severe infections, organ failure, lowered resistance to disease, lifelong deformity and disability, psychological trauma, and an inability to reintegrate into society.
Many types of incendiary munitions cannot be used in a way that allows the combatant to distinguish effectively between soldiers and civilians, military targets and civilian objects. For example, a single typical 155mm artillery round spreads 116 white phosphorus wedges over an area with a radius of up to 125 meters (410 feet). Each wedge burns at about 815° C (1500° F) and produces a thick chemical smoke. These wedges ignite whatever they touch in their broad footprint, burning civilians and setting fire to buildings. As a result, use of incendiary munitions in populated areas severely endangers civilians.
The CCW seeks to protect humans from the two types of harm that incendiary munitions cause. As its full title makes clear, the CCW is concerned with weapons that may be “excessively injurious” or have “indiscriminate effects.”More generally, the CCW’s preamble recalls the “principle of the protection of the civilian population against the effects of hostilities.” The preamble also highlights the international humanitarian law principle, which underlies all of the convention’s restrictions, that the right to “choose methods or means of warfare is not unlimited.”
The rest of this paper will explain how Protocol III is inadequate and lay out possible ways to strengthen its restrictions. Each option is designed with an eye to both decreasing the ongoing humanitarian harm of incendiary munitions and meeting the goals of the CCW.
III. A Broader Definition
The positive humanitarian impact of Protocol III would be increased greatly by broadening its definition to cover all incendiary munitions. The current narrow definition fails to cover certain munitions that cause cruel injuries and indiscriminate harm to civilians.
As written, Protocol III defines an incendiary weapon as a munition “primarily designed” to set fire to objects or to cause burn injuries to persons.This primary design test is too restrictive and allows certain munitions that produce incendiary effects, such as artillery shells containing white phosphorus, to escape regulation. States parties should therefore amend Protocol III to define an incendiary weapon in terms of its effects, rather than in terms of the purpose for which the munition was primarily designed.
Protocol III uses the concept of effects to delineate exclusions to its definition, but states parties should amend that provision as well because it excludes too much. Protocol III does not consider “munitions which have incidental incendiary effects, such as illuminants, tracers, smoke or signaling systems” to be incendiary weapons.This clause could be read to exclude such munitions even if their incidental incendiary effects are substantial. It could also be understood to allow for the intentional use of such munitions as incendiary weapons, so long as they are not primarily designed for that purpose. In an amended protocol, states parties should make clear that smoke-screening, illuminating, and other similar munitions may escape regulation only when their incendiary effects are both minimal and incidental. In addition, states parties should clarify that munitions that fall under the new exclusion cannot be used intentionally as incendiary weapons. The proposed amendments would allow military commanders to retain the ability to use certain illuminants, tracers, and smoke systems as long as the munitions had limited incendiary effects on people and property and were not used deliberately as incendiary weapons.
The proposed amendments would expand the range of munitions covered by Protocol III to include those that may not be primarily designed as incendiary weapons, but that have a strong tendency to create incendiary effects. For instance, M825E1 white phosphorus artillery shells are ostensibly primarily designed as smoke-screening munitions,but they have the effect of starting fires and burning people within a wide radius. The Israeli use of these white phosphorus shells in Gaza in 2009 caused serious bodily harm to civilians, killing at least 12 and injuring dozens more. As well as producing severe burns, the shells indiscriminately set flame to civilian structures over a wide area, including classrooms in a UN compound.US forces used white phosphorus munitions against combatants in Fallujah, Iraq in 2004 expressly for “the combined effects of the fire and smoke” and reportedly also caused civilian casualties.Because these shells were primarily designed to be smoke-screening devices with incidental incendiary effects, however, some have argued Protocol III would not have covered their use, even if Israel and the United States were states parties at the time.
The purpose of CCW is to protect human beings from weapons that are excessively injurious or that have indiscriminate effects. Accordingly, the language of Protocol III should focus on how incendiary weapons actually affect people—the cruel nature of the injuries they cause and their tendency to injure soldiers and civilians without distinction—regardless of the purpose for which weapons are primarily designed. It should not matter if a white phosphorus munition is labeled as a smoke-screen shell. Such a munition should clearly fall under a new definition of incendiary weapon because when a weapon causes substantial incendiary effects, its use should be restricted.
Restrictions based on the effects of a weapon are well established in international humanitarian law.Additional Protocol I to the Geneva Conventions prohibits the use of weapons “of a nature to cause superfluous injury or unnecessary suffering.”The protocol additionally forbids attacks using “means of combat the effects of which cannot be limited as required by this Protocol.”Both of these provisions are part of customary international law.An effects-based test would also be consistent with international jurisprudence. In its Nuclear Weapons advisory opinion, the International Court of Justice discussed whether nuclear weapons could be considered poison or asphyxiating weapons. The Court noted that whether a weapon violates the prohibitions on these weapons depends on whether its “prime, or even exclusive, effect is to poison or asphyxiate,” not on whether it was designed to have those characteristics.
IV. Increased Restrictions on Use
States parties to Protocol III have a further opportunity to advance humanitarian protections by strengthening restrictions on the use of incendiary weapons, which this paper will now define broadly as recommended above. As written, Article 2 of Protocol III bans only use of air-dropped incendiary weapons in “a concentration of civilians.”It imposes weaker regulations on the use of surface-launched incendiary weapons. In a complicated provision regarding surface-launched weapons, it prohibits an attack on a military objective within a concentration of civilians except when the objective is separated from the concentration of civilians and all feasible precautions are taken to minimize effects on civilians.
These rules have proved inadequate to prevent the cruel injuries and indiscriminate harm of incendiary weapons. An outright prohibition on the use of incendiary weapons will give civilians and combatants the strongest protection under international law. If it is impossible to achieve consensus on a blanket ban, however, there are other options that could have important humanitarian benefits.
A Blanket Prohibition
Fully protecting human beings from the cruel and often indiscriminate effects of incendiary weapons requires a total prohibition on the use of these weapons.
An absolute prohibition offers major humanitarian advantages over the existing Article 2 restrictions on the use of incendiary weapons. A blanket ban would protect civilian bystanders from the horrible injuries caused by incendiary weapons, would be easier to apply, would protect military personnel from unnecessary suffering, could reduce stockpiles, and would reinforce the stigma against use.
First, a complete ban would most effectively prevent future injuries to civilians caused by the use of incendiary weapons. Incendiary weapons—whether air or surface delivered—are so prone to being indiscriminate that their use in any context can pose unacceptable risks to civilian bystanders. Any harm that results is exacerbated by the cruel nature of the injuries caused by incendiary weapons, especially their tendency to inflict extreme pain, permanent disfigurement, and death.The best way to achieve complete protection of civilians from this suffering is to prohibit the use of all incendiary weapons.
Second, the clarity of an outright ban on the use of incendiary weapons would make Protocol III easier to apply.A ban would remove the potential for abuse by eliminating debate about what does and does not constitute a concentration of civilians. After the attacks with white phosphorus munitions by US forces in Fallujah, Iraq, some analysts argued that the targeted areas were not concentrations of civilians because much of the city’s civilian population had fled.The question of this interpretation of Protocol III was moot because the United States was not a state party at the time and does not consider white phosphorus to be an incendiary weapon. Nevertheless, it shows that the meaning of concentration of civilians has been open to discussion. An outright prohibition on the use of incendiary weapons would also avoid the need to make difficult judgments about whether all feasible precautions were taken to avoid civilian casualties, as required by Article 2(3). A blanket ban would clarify that all use is impermissible.
Third, a complete ban would protect soldiers from the extreme pain and suffering caused by incendiary burns. Incendiary weapons are an exceptionally cruel way of rendering combatants hors de combat.Beyond their immediate lethality, such weapons often impose long-term physical and psychological disabilities on victims, soldiers and civilians alike. Just as the international community has prohibited the use of blinding lasers, dum-dum bullets, and poison gas to protect soldiers,states parties should prohibit the use of incendiary weapons, in part, to protect military personnel and other combatants.
Fourth, forbidding all use of incendiary weapons would eliminate the primary motivation for states parties to produce, procure, and stockpile these weapons. Reducing the availability of incendiary weapons would in turn lessen the chance that they are misused. In 1984, for example, the Ministry of Defense of El Salvador admitted the country possessed napalm bombs but denied awareness of their actual use.Whether or not the ministry’s claims were true, human rights groups reported frequent use of napalm resulting in serious harm to civilians.Had El Salvador never acquired napalm in the first place, there would have been no opportunity for the bombs to be used, allegedly without the ministry’s approval.
A reduction in stockpiles could further advance antiproliferation efforts by decreasing the opportunities for weapons transfers to non-state armed groups or states not party. By curbing the spread of incendiary weapons, states parties would help to protect both civilians and their own soldiers from the suffering these weapons inflict.
Finally, a key consideration is that a prohibition on all use of incendiary weapons would reinforce the stigma against using the weapons. A clear reaffirmation that incendiary weapons are excessively injurious and have indiscriminate effects would send a message to individual combatants and non-state armed groups, as well as to states party and states not party to CCW, that the use of these weapons is unacceptable in the eyes of the international community.
A blanket prohibition on use could be accompanied by other humanitarian provisions. For example, an amended protocol could prohibit production, transfer, and stockpiling, require stockpile destruction, and oblige states parties to provide assistance for victims. Such provisions have precedent in CCW Amended Protocol II on antipersonnel minesand Protocol V on explosive remnants of war.The Mine Ban Treaty and Convention on Cluster Munitions have even stronger versions of these obligations.If states are willing to pursue a more extensive reworking of Protocol III, these provisions would be a positive addition to an instrument on incendiary weapons.
Prohibitions on particular classes of weapons have a long history.Weapon bans have been motivated by a range of concerns including infliction of superfluous injury or unnecessary suffering on combatants and indiscriminate effects on civilians. As early as 1869, the St. Petersburg Declaration categorically prohibited explosive projectiles weighing less than 400 grammes.Since then, treaties have outlawed poison gas,chemicaland biologicalweapons, antipersonnel landmines,and cluster munitions.Existing CCW protocols already prohibit all use of blinding laser weaponsand weapons that injure people with undetectable fragments.
There has been support for a blanket ban on incendiary weapons in particular for decades. During the League of Nations Conference for the Reduction and Limitation of Armaments (Geneva 1932–1934), the Special Committee on chemical, bacteriological and other weapons proposed prohibiting incendiary bombs.At the CCW preparatory conference in 1979, Austria, Egypt, Ghana, Jamaica, Mexico, Romania, Sudan, Sweden, Switzerland, Togo, Venezuela, Yugoslavia, and Zaire put forward a proposal prohibiting all use of incendiary weapons.During the CCW diplomatic conference in 1979in 1980 in 19, a delegate from Mexico expressed the view that a majority of states supported a total ban.
More recently, in its 1991 international humanitarian law manual, Sweden said, “There is a need to supplement the present Protocol III so that the agreement constitutes a complete prohibition of incendiary weapons. In this way, protection of civilians could be further enhanced, and this should be extended to cover combatants.”In addition, at least three states, Andorra, Hungary and the Former Republic of Yugoslavia, have banned use of incendiary weapons in national laws, and at least one, Colombia, has prohibited it in a military manual.While these proposals and policies have not led to an absolute prohibition at the international level, the time is ripe to negotiate one now. Recent conflicts have shown how incendiary weapons, broadly defined, produce ongoing harm, and humanitarian concerns are increasingly important to weapons treaties.
If it is not possible to secure an outright prohibition on the use of incendiary weapons in the CCW forum, states parties should at the very least change the definition and prohibit use of all models of these weapons in civilian areas. States parties could also impose strict standards for when incendiary weapons may be used even outside of civilian areas and prohibit antipersonnel use of incendiary weapons.
Prohibition on Use of All Incendiary Weapons in Civilian Concentrations
Article 2(2) of the protocol already prohibits the use of air-delivered incendiary weapons against targets within a concentration of civilians. States should at least amend this provision to apply the same restriction to all incendiary weapons, including surface-launched models.
Although Article 2(3) imposes some restrictions on the use of non-air-delivered incendiary weapons against military targets within concentrations of civilians,its complicated rules, described above, fail to protect civilians adequately from surface-launched incendiary weapons.While air-dropped napalm was the central concern during the initial CCW negotiations,recent reports concerning the use of munitions with incendiary effects have mainly involved surface-launched munitions such as artillery projectiles.The mechanism by which incendiary weapons are delivered, be it plane, artillery, ground rocket, mortar, or any other, is irrelevant from a humanitarian standpoint. A prohibition on all use of incendiary weapons against targets within concentrations of civilians would further the CCW’s overarching purpose of “protect[ing] the civilian population against the effects of hostilities.”
Some states, such as Germanyand France,already prohibit the use of all incendiary weapons in civilian areas regardless of the weapons’ delivery mechanism. Such an option was also considered for Protocol III at the negotiating stage. An Indonesian proposal circulated at the CCW Preparatory Conference in 1979 would have forbidden the use of all incendiary weapons (both air-dropped and surface-launched) against military objectives “within civilian population centres.”It is an opportune moment to revive this proposal and strengthen the restrictions on incendiary weapons.
Presumption of Illegality
Under the proportionality test, international humanitarian law prohibits “any attack which may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof, which would be excessive in relation to the concrete and direct military advantage anticipated.”As described above, attacks involving incendiary weapons, especially in concentrations of civilians, are highly likely to impose excessive harm to civilians.
Even outside of civilian concentrations, the indiscriminate nature of incendiary weapons makes them prone to injuring civilians and damaging civilian property. In order better to protect civilians, states could adopt a presumption that the use of incendiary weapons outside of civilian concentrations is disproportionate and thus illegal except where states can show that expected military advantage substantially outweighs risk to civilians.
Such a presumption of illegality would compel commanders to investigate the civilian consequences of striking possible targets thoroughly before authorizing the use of incendiary weapons. Because the humanitarian harm resulting from the use of incendiary weapons is foreseeable and severe, commanders should have to present extraordinarily strong military reasons for using them, if they are allowed to use them at all. Narrowing the range of permissible attacks would decrease the number of cases in which incendiary weapons are actually used, reducing the associated human suffering.
Prohibition of Antipersonnel Use
In light of the terrible effects of incendiary weapons on human beings, states could also amend Protocol III to prohibit the targeting of military personnel and other combatants. Protocol III already prohibits states from targeting civilians.It does not address use on combatants, however, and the humanity of soldiers is deserving of respect even in times of armed conflict.
A new provision on antipersonnel use would help reduce the risk of soldiers being hit and harmed by these excessively injurious weapons. The International Committee of the Red Cross’s Commentary to Additional Protocol I to the Geneva Conventions indicates that, under existing international law, incendiary weapons must “not be used in such a way that they will cause unnecessary suffering.”Because such weapons are prone to causing extreme pain, disability, and disfigurement, states parties should consider codifying that principle in Protocol III and adopting a clear prohibition on using such weapons against military personnel as well as civilians.
Prohibiting the targeting of combatants will also reinforce the general norm against the use of incendiary weapons, making all kinds of use less likely. Narrowing the range of circumstances under which states could permissibly use incendiary weapons would reduce the reasons to stockpile such weapons in the first place. Sending the message that incendiary weapons are so cruel that they cannot be used even on soldiers could further reinforce the stigma associated with the weapons.
There is international precedent for prohibiting the antipersonnel use of particular weapons. For example, the 1868 St. Petersburg Declaration was adopted to prevent individual soldiers from being targeted with certain explosive projectiles,and the 1869 Declaration on the Use of Bullets Which Expand or Flatten Easily in the Human Body, banning dum-dum bullets, had similar motivations.
There have also been a number of proposals and policies to prohibit the use of incendiary weapons against combatants. During the 1979 CCW Preparatory Conference, the working group on incendiary weapons circulated, in brackets, a clause declaring that “[i]t is prohibited to use incendiary weapons against combatants as such.”Indonesia,Nigeria,and the USSRproposed similar provisions although with exceptions. More recently, Belgium has prohibited antipersonnel use of incendiary weapons in its national military manual.The United Kingdom has similarly stated in its military manual, “[W]eapons such as napalm and flame-throwers …. are governed by the unnecessary suffering principle so that they should not be used directly against personnel.” In addition, according to the UK minister of state, while the UK government does not consider white phosphorus unlawful, it is “very clear that it should not be used as an anti-personnel weapon and certainly not in a civilian environment.” An amendment to Protocol III would make such positions binding at the international level.
In 1980, states came together to take steps to mitigate the terrible effects that incendiary weapons inflict on human beings. Even then, many states were concerned that Protocol III’s provisions would not be enough to address the horrors of incendiary warfare.Their concerns proved well founded: incendiary weapons have continued to impose unacceptable suffering around the world.States parties now have the opportunity to revisit the protocol to put in place measures to fulfill the humanitarian objectives of the CCW.
By adopting a more comprehensive definition of incendiary weapons, states can ensure that Protocol III covers all such weapons that are likely to cause excessively injurious or indiscriminate incendiary effects. Expanding the definition is key to bringing de facto incendiary weapons, such as white phosphorus shells, within the ambit of the CCW.
States should also reduce the harm incendiary weapons cause by imposing stronger restrictions on their use. A total prohibition on the use of these weapons would maximize the protection of civilians. If such a prohibition is not possible within the CCW forum at this point, states should, at the very least, adopt measures to prohibit use of all incendiary weapons in civilian areas. They should also seriously consider a presumption that the use of incendiary weapons is unlawful, even outside of civilian concentrations, and a prohibition on antipersonnel incendiary attacks. Only by amending the text of Protocol III to address its weaknesses can real progress be made in preventing future suffering from incendiary weapons.

 Interestingly, while Australia’s 1994 Commanders’ Guide restates Protocol III’s design-based definition, it also states that “incendiaries include weapons such as … white phosphorous.” International Committee of the Red Cross (ICRC) Customary International Humanitarian Law Database, “Practice Relating to Rule 84: The Protection of Civilians and Civilian Objects from the Effects of Incendiary Weapons,” http://www.icrc.org/customary-ihl/eng/docs/v2_cha_chapter30_rule84 (accessed August 4, 2011).

 The 2008 Convention on Cluster Munitions demonstrates how even a convention with a design-based definition can take effects into account. The convention defines cluster munition as being “designed to disperse or release explosive submunitions….” The convention then looks to the humanitarian effects of weapons to determine which are safe to exclude. It states that its definition of cluster munition does not include munitions with certain specific technical characteristics because they “avoid indiscriminate area effects and the risks posed by unexploded submunitions.” Convention on Cluster Munitions, adopted May 30, 2008, Diplomatic Conference for the Adoption of a Convention on Cluster Munitions, CCM/77, entered into force August 1, 2010, art. 2(2)(c) (emphasis added).
