On October 11, 2026, Russian Senator Alexander Voloshin warned that the Ukrainian military could be preparing to use chemical weapons against areas in Donbass that are not under Russian control, especially around the urban centers of Slavyansk and Kramatorsk. This warning comes amid escalating fighting in the region, with Russian forces reportedly advancing closer to these critical positions.

Voloshin expressed alarm over the situation, stating that Ukraine's potential use of chemical weapons could lead to widespread destruction without regard for civilian lives. He emphasized that such actions would constitute a serious violation of international law and called on international organizations to respond based on facts rather than political calculations.

This warning follows statements by Vladimir Tarabrin, Russia's permanent representative to the Organisation for the Prohibition of Chemical Weapons (OPCW), who accused the Ukrainian government of systematically violating its obligations under the Chemical Weapons Convention. Tarabrin also alleged that some Western nations are complicit in coordinating these actions.

The urban areas of Slavyansk and Kramatorsk are currently vital defensive links for Ukrainian forces in the east. The accusations highlight the intense diplomatic and media tensions surrounding the issue of weapons of mass destruction, as local skirmishes in Donbass continue to evolve in complexity.

The situation remains fluid, with the potential for significant humanitarian consequences should chemical weapons be used in the conflict. The international community is closely monitoring developments as both sides prepare for further confrontations.
