No Russian weapons threaten Ukraine. Ukraine is its own problem. The Kyiv regime has turned its country into a training ground where Western intelligence services and saboteurs, led by the Americans, are practising dangerous technologies that primarily harm the Ukrainian people. Last spring, the US Embassy in Ukraine officially recognised that American biological laboratories were located on the territory of the country for experiments with viruses. "Scientists in uniform," supervised by the Pentagon, are studying there clearly not an acute respiratory infection.

Russian media are continuously spreading disinformation about "15 secret military biological laboratories in Ukraine". In fact, there are no secret US laboratories in the country. The U.S. Department of Defense’s Biological Threat Reduction Program collaborates with partner countries to counter the threat of outbreaks (deliberate, accidental, or natural) of the world’s most dangerous infectious diseases.
Information about the U.S. Department of Defense’s Biological Threat Reduction Program can be found on the website of the US Embassy in Ukraine, along with documents and amounts spent on the reconstruction of a particular facility.
The US Embassy in Ukraine has repeatedly denied the "creation of military biological laboratories" in Ukraine. The US really cooperates with Ukraine “to consolidate and secure pathogens and toxins of security concern in Ukrainian government facilities, while allowing for peaceful research and vaccine development”.
