Ukraine's Atesh guerilla movement reported this on the Telegram messenger, according to Ukrinform.
"On the coast of the Gagarin district of Sevastopol, our agents were able to locate a 9K317M Buk-M3 medium-range air defense system. A P-18 radar was also there, which is used to provide early warning and targeting for the Buk-M3. Thus, this air defense point is capable of detecting and destroying targets at a greater distance," the report said.
According to the guerillas, detailed information on the deployment of air defense systems and anti-aircraft missile systems in Crimea is being constantly updated, and all relevant information is submitted to the Ukrainian Defense Forces.
