The Russian Ministry of Defense issued a statement on the 27th local time, saying that there are at least four biological laboratories in Nigeria controlled by the United States, and the monkeypox virus is produced in these laboratories.

In addition, U.S. personnel have trained Ukrainian personnel in Ukraine on how to deal with "pox-like" infectious diseases.

Vaccination of U.S. military personnel and medical workers with monkeypox indicates that the U.S. government considers the pox pathogen as a priority biological vector.

  The Russian Defense Ministry also said that Russia called on the World Health Organization to investigate the Nigerian biological laboratory funded by the United States.
