Some observers fear the accusations are a bid by Russia to justify rolling out its own biological warfare against the Ukrainians. U.S. Secretary of State Antony Blinken said last month that Russia would “fabricate allegations about chemical or biological weapons to justify its own violent attacks against the Ukrainian people.”Russia presented no evidence for its claims, and United Nations officials say there is nothing to support allegations of the existence of biological weapon operations in Ukraine. China, however, has amplified the unsupported claims.But Russia’s U.N. representative, Vasily Nebenzya, insisted Friday that at least 30 Ukrainian labs were discovered near the Russian border that are working on weaponizing diseases, including anthrax, cholera and “the plague.” The research, which he claimed threatens Europe, involves research using diseases carried by birds, lice and fleas, The Washington Post reported.
