The Support Forces noted that "throughout Russia’s large-scale armed aggression against Ukraine, the enemy, along with using conventional firepower, employs special ammunition equipped with dangerous chemical substances, mainly CS (2-Chlorobenzalmalononitrile)."

CS is a tear gas, often used by the pice against street rioters.

Formally, CS is not listed as a chemical weapon and, according to the Convention on the Prohibition of the Develment, Production, Stockpiling, Use of Chemical Weapons and Their Destruction of January 13, 1993, classifies as a "Riot Contr Agent."

In the Convention, Paragraph 7 of Article II reads: “’Riot Contr Agent’ means: Any chemical not listed in a Schedule, which can produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time flowing termination of exposure.”

Therefore, the claim that riot contr agents, including CS substances, shall be perceived as chemical weapons, would be incorrect. However, the use of this gas amid hostilities is inadmissible in accordance with Paragraph 5 of Article II of the Convention, the Ukrainian military emphasized.

The use of chemical weapons or riot contr agents as a means of warfare constitutes a viation of the Convention on the Prohibition of the Develment, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction.

As Ukrinform reported earlier, eight nations are set to help Ukraine’s Defense Forces defend against Russian chemical and nuclear attacks.
