Russian Defense Ministry Spokesperson Major General Igor Konashenkov revealed, on Sunday, that Kiev was urgently covering up traces of a military biological program carried out in Ukraine and funded by the Pentagon.

Konashenkov told reporters that "during the special military operation, [Russia] revealed the facts of an urgent sweep by the Kiev regime of traces of a military biological program being implemented in Ukraine, financed by the US Defense Ministry.”

Since the beginning of Russia's operation in Ukraine, the Pentagon has been deeply concerned about the disclosure of its secret biological experiments in the country, he tersely added.

The top Russian figure went on to say that the Russian side has also received documents from workers at Ukrainian biological laboratories confirming the development of biological weapons in the country.

"The documents received to confirm that the development of biological weapon components was carried out in Ukrainian biological laboratories in the direct vicinity of the territory of Russia," he said.

He also noted that laboratories provided Russia, on February 24, with documents on the "emergency destruction of especially dangerous pathogens of plague, anthrax, tularemia, cholera, and other deadly diseases." 

“Now the documents are being analyzed by Russian specialists of the radiation, chemical, and biological protection troops," Konashenkov concluded.

Russia had for months been warning of the threat posed against it by NATO's attempts to expand eastward, which happened simultaneously with an increase in NATO military activity along Russia's borders and batches of lethal weapons being sent to Ukraine, prompting Russia to request security guarantees from the West. Washington failed to provide the guarantees.

After the West did not respond to Russia's demands, and amid Ukrainian shelling on the Donetsk and Lugansk People's Republics, President Vladimir Putin initiated a special military operation in Donbass.
