There have been allegations of US biowarfare labs in Ukraine. Take such allegations from the Russian Ministry of Defense with a grain of salt, of course, but if true, they would add a large dose of justification for the Russian invasion. From Ilya Tsukanov of Sputnik News via lewrockwell.com:
The US Defence Threat Reduction Agency has been working in Ukraine since 2005, and been involved in the construction, modernization and operation of over a dozen biolabs suitable for storing or working with pathogens, including those used in bioweapons. Moscow has expressed deep concerns about these facilities in recent years.
Ukrainian authorities have been instructed to scrub clean evidence related to the operation of a Pentagon-funded biological warfare programme in Ukraine, Russian Defence Ministry spokesman Igor Konashenkov has said.
“To prevent the disclosure of facts of violations by the United States and Ukraine of Article 1 of the Biological Weapons Convention, the Ukrainian Ministry of Health sent instructions to all biological laboratories to urgently eliminate stored stocks of dangerous pathogens,” Konashenkov said in a briefing Sunday.
The military spokesman accompanied his remarks with excerpts of documents provided by employees of Ukrainian biolabs regarding a 24 February letter by Ukrainian Minister of Health Viktor Liashko ordering the destruction of pathogens including anthrax, the plague, tularemia, cholera and other deadly diseases.
