It is feared that Russian forces may be ready to use toxic sarin nerve gas in combat areas where their offensives have suffered the biggest setbacks, reported Ukraine’s Center for Countering Disinformation.

According to earlier reports, on March 17 and March 20 Russian military officers deployed for combat in Ukraine were administered Pralidoxime chloride and Atropine that are usually used as antidotes against toxic nerve agents like sarin gas.
