Russian forces have deployed Shahed-type "kamikaze" drones carrying toxic substances to attack Ukraine, the Center for Countering Disinformation at Ukraine's National Security and Defense Council said on April 16.

Russia has been intensifying its use of chemical agents on the battlefield in Ukraine, with Kyiv recording over 6,000 cases of use of munitions containing hazardous chemicals between February 2023 and 2025.

A capsule with CS gas, a riot control agent, has been found in one of the Russian drones, the center said, adding it had verified the information with Ukraine’s security services and the State Emergency Service.
