On March 6 local time, the Russian Ministry of defense held a press conference to report the latest progress of Russia's military action against Ukraine.

The briefing said that the Russian army has basically disarmed the combat effectiveness of the Ukrainian armed forces air force, and warned regional neighbors not to provide airports as bases for Ukrainian fighters.

The Russian Defense Ministry also said that Russia found a military biological plan funded by the United States and implemented in Ukraine during military operations. Several Ukrainian biological laboratories near the Russian border have been engaged in the research and development of biological and chemical weapons. After the Russian military operations began in Ukraine, these laboratories destroyed viruses that could cause plague, anthrax and cholera. At present, Russia has released relevant materials.
