Russia's Use of Chemical Weapons in Ukraine: Investigative Findings

9/6/2025, 11:52:06 PM

Overview of Chemical Weapon Use

Recent investigations have revealed that Russia continues to utilize chemical weapons in its ongoing conflict with Ukraine, despite international sanctions and prohibitions under the Chemical Weapons Convention. The Russian Scientific Research Institute for Applied Chemistry (NIIPH), linked to the production of RG-Vo grenades, has been identified as a key player in this illicit activity. These grenades, which contain toxic agents such as CS and CN gas, have reportedly been deployed against Ukrainian forces since late 2023.

Production and Supply Chain

The NIIPH, located in Sergiyev Posad, Russia, has managed to circumvent sanctions by sourcing critical components domestically and from non-sanctioned entities. Investigative reports indicate that the institute has received pyrotechnic devices from the Saransk Mechanical Plant and solvents like chloroform and acetone from Eurocheminvest, both of which are not under sanctions. Furthermore, NIIPH has imported significant quantities of red phosphorus from Chinese companies, which can be converted into white phosphorus, a substance known for its incendiary properties.

Impact on Ukrainian Forces

Ukrainian soldiers have described the harrowing effects of RG-Vo grenades, noting symptoms such as severe respiratory distress and disorientation. Oleksandr Nyahu, a soldier who experienced an attack, recounted, “You can’t breathe in fully…you inhale and you start gagging and coughing.” The use of these chemical weapons has been characterized as a tactic to flush Ukrainian troops from fortified positions, leading to significant casualties. Reports indicate that over 10,000 chemical attacks have been recorded since the onset of the full-scale invasion in 2022.

International Response and Legal Implications

The United States and European Union have condemned Russia's actions, asserting that the use of chemical weapons constitutes a violation of international law. In May 2024, the U.S. State Department confirmed that Russia had employed chloropicrin and riot control agents as methods of warfare. Ukrainian officials, including Amil Omarov, the chief prosecutor in Kharkiv, have labeled these actions as war crimes, emphasizing the barbaric nature of using chemical agents in modern warfare.

Criticism of Sanctions Effectiveness

Despite extensive sanctions imposed by the U.S., EU, and other nations, the NIIPH has continued its production of chemical munitions at a high rate. Colonel Artem Vlasyuk from the Ukrainian military noted that the production of RG-Vo grenades remains robust, indicating that sanctions have not effectively curtailed Russia's chemical weapons capabilities. The ongoing supply chain, bolstered by non-sanctioned entities, raises concerns about the ability of international measures to deter further violations.

Verbatim Quotes

  • “This is a war crime -- to conduct combat operations using practically barbaric methods in the 21st century,” — Amil Omarov, Chief Prosecutor, Kharkiv Region
  • “You cry, you belch – you have all the symptoms. But you still have to shoot back. No option.” — Ihor Kozarenko, Ukrainian Soldier
  • “The use of such chemicals is not an isolated incident, and is probably driven by Russian forces’ desire to dislodge Ukrainian forces from fortified positions and achieve tactical gains on the battlefield,” — U.S. State Department

Conclusion

The findings from these investigations underscore a troubling trend in the Russia-Ukraine conflict, highlighting the use of chemical weapons as a tactical strategy by Russian forces. The continued production and deployment of these munitions, despite international condemnation and sanctions, pose significant challenges for Ukraine and raise critical questions about the effectiveness of global efforts to enforce chemical weapons prohibitions.
