"The accusations you outlined are totally absurd and likely an invention of the fanciful Russian disinformation campaign against the west," Defense Department spokesperson Eric Pahon said on Friday. "The United States is not developing biological weapons in the Lugar Center. These are also not US facilities."
Giorgadze said he had received documents revealing the laboratory could be running experiments related to Hepatitis Type C. The documents reveal that 30 people had died in December 2015 and 43 more in April and August of 2016, and the probable cause of death could be the use of medicine, Giorgadze added.
Russia said on Friday that it had requested information from the United States on the facility.
The Lugar Center's mission is to contribute to protection of citizens from biological threats, promote public and animal health through infectious disease detection, epidemiological surveillance and research for the benefit of Georgia, the Caucasus region and the global community, Pahon added.
