The Russian mission to the United Nations has presented on several occasions evidence about the United States using biological facilities in Ukraine for the purpose of conducing experiments with various agents.
In September, the Russian Defense Ministry in Geneva presented evidence of the United States' military-biological activity in Ukraine.
