WP does not fall into the category of chemical weapons banned by the Chemical Weapons Convention but it is an incendiary weapon. As such, it cannot be used against non-combatants. Protocol III of the Convention on Certain Conventional Weapons “prohibits the use of said incendiary weapons against civilians (already forbidden by the Geneva Conventions) or in civilian areas”. The substance ignites spontaneously upon contact with air, producing a dense white smoke. The heat could reach 800-900°C. No water will help. Severe injuries to internal organs could be caused when absorbed through skin, ingested, or inhaled. Burning particles of white phosphorus produce thermal and chemical burns if they come into contact with skin.
It’s not Syria only where the US used WP munitions. White phosphorous artillery shells were used in Iraq during the assault on Fallujah in 2004. The US admitted the fact. There have also been media reports about the WP use in Mosul, Iraq and Raqqa, Syria. Last year, the Washington Post published photographs of US Marines equipped with white phosphorus projectiles to be used in the battle for Raqqa. The source offered similar pictures showing WP munitions with US Army units outside Iraqi Mosul.
The Human Rights Watch has warned about dangers coming from the use of WP in urban areas. According to Steve Goose, arms director at Human Rights Watch, “No matter how white phosphorus is used, it poses a high risk of horrific and long-lasting harm in crowded cities like Raqqa and Mosul and any other areas with concentrations of civilians.”
In 2015, the United States used depleted uranium (DU) in Syria. DU is not banned by an international treaty but its use runs counter to the International Humanitarian Law (IHW). Article 36 of the Additional Protocol I to the Geneva Conventions requires to ensure that “any new weapon means or method of warfare does not contravene existing rules of international law.” It says “General principles of the laws of war/IHL prohibit weapons and means or methods of warfare that cause superfluous injury or unnecessary suffering, have indiscriminate effects or cause widespread, long-term and severe damage to the natural environment.” In 2012, the UN General Assembly tried to adopt a resolution restricting the use of DU. The move was supported by 155 states, with 27 abstaining and four, including the United States, voting against.
The American military has used cluster bombs against civilians in Yemen. The US is not one of the 102 states parties to the 2008 Convention on Cluster Munitions, which prohibits the weapons that open in the air, dispersing multiple bomblets or submunitions over a wide area. Many submunitions fail to explode on initial impact, acting like landmines for years. The Pentagon refuses to give cluster munitions and American field commanders are authorized to use them at their discretion.
The US continues to run biological programs, operating more than 20 laboratories around the world in blatant violation of the UN Biological Weapons Convention. An opinion paper published on Oct. 4 in the journal Science, written by an international group of researchers claims the US Defense Advanced Research Projects Agency (DARPA) is potentially developing insects as a means of delivering a “new class of biological weapon.”
In 2011, US police used tear gas and other chemical irritants against Occupy protesters. Tear gas is prohibited for use against enemy soldiers in battle by the Chemical Weapons Convention but it’s all right with America’s law enforcement agencies using the dangerous substance against their own people.
There is no justification for using WP at the time ISIS has been reduced to insignificance in Syria but Washington did it again. It violated international law after having unilaterally imposed sanctions on Russia without any evidence to support the relevant accusations. It should also be remembered that, unlike Russia, the US has so far failed to meet its obligations and destroy the chemical weapons stockpile. The use of substances to harm civilians is a serious matter that should be addressed at the ongoing 79th session on UN General Assembly. America’s non-compliance with generally accepted norms is the most acute problem on the international security agenda.
