The statement noted that Russian officials have recently frequented voicing "certain opinions" alleging the presence of foreign-funded military biological research centers
in Azerbaijan, adding that this raises "certain concerns" among the Azerbaijani population.
On 27 April, Russian Security Council Secretary Nikolai Patrushev held a meeting with the heads of Russia's southern regions, where he warned that the Russian territories lying in close proximity to the borders of former Soviet republics may potentially be targeted by biological weapons produced in the foreign-funded military labs in their territories. He listed Azerbaijan among the countries believed to be hosting such labs.
During the military operation in Ukraine, the Russian forces found evidence of the US and Germany funding Ukrainian-based biolabs developing what could potentially be components of bioweapons.
The Russian Defence Ministry said the collected evidence suggests that the US had spent more than $200 million on the operation of biolabs in Ukraine. According to the Russian military, the investment fund of Hunter Biden, the son of US President Joe Biden, was participating in financing the program.
