During the 111th session of the OPCW Executive Council from March 10 to 13, Ukraine raised serious allegations about Russia's use of chemical weapons in its military operations. The Ukrainian delegation documented over 12,500 incidents involving the use of Russian chemical munitions.

The Ukrainian Embassy in the Netherlands commented that these actions are violations of international law and pose risks to the global non-proliferation regime. As the conflict nears its fourth year, these claims are increasingly critical.

Key Details

Ukrainian representatives emphasized that the systematic use of chemical weapons not only threatens immediate battlefield conditions but could also compromise broader international security. Andriy Kostin, head of the Ukrainian delegation, urged for the OPCW to implement effective mechanisms to identify and hold accountable those involved in chemical weapons use.

The session highlighted new methods for delivering chemical agents, including the use of drones to spread chemicals over enemy positions. This development alarmed international observers and human rights organizations.

Background

Ukraine's demand for accountability aligns with support from several European nations, including France, Germany, the Netherlands, Sweden, and the United Kingdom, all advocating for repercussions for Russia’s actions. The delegation recalled previous examples of Russia's use of chemical agents, notably the Skripal and Navalny poisonings, reinforcing claims of Russia’s violations of international conventions on chemical weapons.

During the session, Ukraine secured its position on the OPCW Executive Council, while Russia faced its third consecutive defeat in re-election efforts. This outcome reflects a shift in global perspectives regarding the ongoing conflict.
