MOSCOW, March 17 (Xinhua) -- A laboratory in Ukraine's second-largest city of Kharkov has studied transmitting diseases to humans through bats under U.S. control, the Russian Defense Ministry said Thursday.
"Specialists of the Russian Radiation, Chemical and Biological Defense Forces have studied original documents revealing the details of the U.S. implementation of a secret project to study the ways of transmitting diseases to humans through bats in a laboratory in Ukraine's Kharkov," the ministry's spokesman Igor Konashenkov said.
"According to the documents, these studies were carried out on a systematic basis and under direct supervision of U.S. specialists for many years," he told a briefing.
The Russian Defense Ministry will publish a new package of documents on the developments of Ukrainian biological laboratories, which were received from lab employees, he added.
Russia has expressed grave concerns over U.S.-funded biological laboratories in Ukraine, where various kinds of dangerous viruses were stored and studied.
Last week, U.S. Undersecretary of State for Political Affairs Victoria Nuland testified before a Senate Foreign Relations Committee hearing on Ukraine, admitting "Ukraine has biological research facilities."
"We are working with the Ukrainians on how they can prevent any of those research materials from falling into the hands of Russian forces should they approach," she said.
On March 11, Ukrainian President Volodymyr Zelensky said in a video post on his facebook account that "no chemical or any other weapons of mass destruction were developed on my land."
