The Main Intelligence Directorate uncovered a secret Russian biological laboratory containing dangerous viruses
A classified complex of biological laboratories has been discovered in Russia’s Tver Region, where Russian specialists are conducting experiments with dangerous viruses and pathogenic microorganisms.
According to him, new, state-of-the-art laboratories with enhanced security measures for working with biological samples and chemical substances were built on the site of an old complex on a separate island, where “unauthorized persons” have no access.
"Officially, the facility studies diseases of domestic animals—brucellosis, tuberculosis, and other bacterial and viral diseases. However, in May, the FMBA (Federal Medical-Biological Agency of Russia—ed.) began recruiting a lab technician for the island, whose duties explicitly include working with pathogenic biological agents of Groups I–IV. “According to the Russian classification, Group I includes agents that cause particularly dangerous and deadly infections that are easily and rapidly transmitted from person to person,” Chernyak said.
According to him, the facility is guarded at the highest level. Its security is ensured by units of the Federal Security Service and the Federal Guard Service, an entire military garrison, as well as anti-aircraft systems and electronic warfare capabilities.
As reported by the Main Intelligence Directorate of the Ministry of Defense of Ukraine, the secret military complex of biological laboratories in the Tver Region is officially named the “Center for Experimental Physiology”; it is located on Lysy Island in the middle of the Vyshnyovolotsk Reservoir.
Since 2023, the waters around the island with the biological laboratories have been closed to fishing, swimming, or boating as a “specially protected area of regional significance.”
The reservoir supplies fresh water to a number of settlements, including the city of Vyshniy Volochek, and is the source of the Tverets River, which flows into the Volga.
If dangerous pathogens or chemicals from the biolaboratories were to enter the reservoir, the consequences of an outbreak of epidemics and infections could be catastrophic not only for the region’s population but also for all of Russia, the GUR noted.
The biolaboratory complex project was implemented by order of Russian dictator Vladimir Putin as a project of special importance—designed to “ensure Russia’s defense capability and security.” Formally, it was incorporated into the structure of the Federal Medical and Biological Agency.
“As is well known, in the spring of 2026, an outbreak of foot-and-mouth disease among cattle occurred in Russia, which Moscow tried to conceal from the world and its own population. It cannot be ruled out that this and other similar cases may be the result of failed Russian experiments with viruses, bacteria, and other pathogens,” the Main Intelligence Directorate noted.
Andriy Chernyak, a representative of the Main Intelligence Directorate, spoke about this in an interview with the Kyiv Post.
Russia is projected to face nearly a decade of economic stagnation.
A large-scale disinformation campaign was uncovered in Poland and the Czech Republic, during which a fabricated story was spread about Warsaw’s alleged territorial claims on Prague. The perpetrators created a fake “Czech Radio” website, forged social media accounts, and even a fake document regarding the transfer of 638 hectares of Czech territory to Poland.
