At the 111th session of the Organization for the Prohibition of Chemical Weapons (OPCW) Executive Council in The Hague from March 10 to 13, Ukraine revealed concerning statistics regarding Russia's use of chemical weapons. Ukrainian representatives stated that Russia had deployed chemical agents over 12,500 times on the battlefield.

Systematic Violations

The Ukrainian delegation emphasized that this systematic employment of hazardous chemicals represents a grave threat to global non-proliferation efforts and international security. As the fourth anniversary of Russia's full-scale invasion nears, the risks associated with chemical warfare are increasing.

Urgent Request for Action

Andrii Kostin, head of the Ukrainian delegation, called for stronger mechanisms within the OPCW to verify the usage of chemical weapons and to identify perpetrators. He highlighted the necessity for accountability for all involved, including those who execute and support these actions.

Historical Context

The report referenced previous incidents involving chemical agents, including the poisonings of Sergei Skripal and Alexei Navalny, linking Russia's actions to broader trends of chemical weapon use beyond Ukraine. Ukraine has collaborated with France, Germany, the Netherlands, Sweden, and the UK to demand accountability for Russia's violations of the Chemical Weapons Convention.

Trends and Support

Ukrainian officials noted alarming trends, such as the drone-delivery of toxic chemicals in conflict zones. They expressed gratitude for the OPCW's ongoing support, particularly its expert assistance for national investigations in Ukraine. Financial contributions from partner nations aimed at boosting Ukraine's capabilities to confront chemical threats were also recognized.

Ukraine reaffirmed its commitment to the Chemical Weapons Convention and pledged continued collaboration with the OPCW and its allies to strengthen global bans on chemical weapons and ensure accountability.
