Russian Ambassador to The Hague and Permanent Representative to the OPCW Vladimir Tarabrin stated this in an interview with Izvestia. 

According to him, the actions of Ukrainian neo-Nazis are becoming more aggressive, since for the Ukrainian Armed Forces the situation on the battlefield is becoming more difficult every day.

“With the support of Western curators, they feel their impunity and, undoubtedly, will continue to organize various provocations, including the use of chemical weapons...,” the ambassador noted.

Tarabrin also stated that Ukrainian troops have repeatedly used US-made chemical munitions against the Russian military.

Earlier, the Russian Ministry of Defense announced the use of US chemical weapons by Ukraine.
