MOSCOW, March 10. /TASS/. One of the documents obtained by the Russian Armed Forces confirms that all high-risk studies in Ukrainian biological laboratories were conducted under the guidance of specialists from the US, Chief of Russia’s radiation, chemical and biological protection force, Igor Kirillov said on Thursday.

"One of the documents confirms that all high-risk studies are conducted under the direction of specialists from the US," Kirillov noted.

According to him, "[the materials] clearly refute the US statement that only Ukrainian scientists work in the Pentagon biolabs in Ukraine without the intervention of the US biologists," Kirillov pointed out.

Meanwhile, the US disparagingly treated the Ukrainian specialists. "Attention is paid to the extremely humble wages by the US standards. This demonstrates a low assessment of the professionalism of Ukrainian specialists and disregard for them from their US colleagues," he explained.

Kirillov underscored that the accounting documents confirm the fact that the US Department of Defense paid money for participating in studies directly without the involvement of intermediaries.
