As the Russia-Ukraine conflict continues to unfold, the Russian government claimed that its forces found the US is using laboratories in Ukraine to develop biological weapons, but the US denied such claims and accused Russia of spreading "disinformation." According to the information provided by the US to the Conference of Parties of BWC, it has 336 laboratories around the world. The international community has long-held serious concerns about the biological military activities conducted by the US at home and overseas, urging the US to clarify itself with transparency and evidence.
