The Lugar laboratory used by Americans developed biological weapons that would kill 70% of Russia’s population.
No evidence given.
Conspiracy theory and recurring pro-Kremlin disinformation about US developing biological and/or chemical weapons mostly in order to use them against Russia. See e.g. the Disinfo Review from 4 October 2018.
The Central Public Health Reference Laboratory (CPHRL) - the so called Lugar Laboratory - was opened in 2011 under the Framework Agreement signed in 1997 and the Agreement on Cooperation in the Area of Prevention of Proliferation of Technology, Pathogens and Expertise Related to the Development of Biological Weapons signed between the U.S. Department of Defense and the Georgian Defense Ministry in 2002. The United States provided a total of USD 350 million for the construction and technical equipment of the laboratory. In 2013 the laboratory moved to subordination of the National Center for Disease Control and Public Health (NCDC) and from 2018 the Government of Georgia will assume responsibility for full funding and operation of the Lugar center and laboratory network.
