The Russian Defense Ministry is still investigating data related to the military biological programs of the United States and NATO in Ukraine. Information received by the Ministry raises questions about the US allegations that Kiev does not have the infrastructure to produce and develop bioweapons, according to Igor Kirillov, the Russian armed forces' head of the radiation, chemical, and biological defense, on Wednesday.

"The Ministry of Defense of the Russian Federation continues to study information on the implementation of the military biological programs of the United States and its allies in the NATO bloc on the territory of Ukraine," he told a briefing. He added, "In addition, on March 9, three unmanned aerial vehicles equipped with 30-liter containers and equipment for spraying formulations were found on the territory of the Kherson region. At the end of April, 10 more drones were found near the village of Kakhovka."

Kirillov also said that earlier Ukraine requested the manufacturing company if it was possible to equip Bayraktar drones with aerosol equipment.

Leaked correspondence between the Turkish defense company, Baykar, and Motor-Sich, an aircraft manufacturer in Ukraine, exposes Ukraine's questions directed to the company, asking them whether their UAVs can "spray aerosols with a capacity of more than 20 liters" to which Baykar answered, "No".

Another question that struck as alarming is whether the UAV can travel more than 300 km, which may pose a threat to Russian security as the vehicle, which is intended to spray aerosol, can travel for use in Russian territory. 

The Russian Defense Ministry said that such questions could prove that Kiev was developing delivery vehicles for biological weapons with the possibility of using them against Russia.
