 Special operation in Crimea. Ukrainian security service and Navy deal powerful blow to Saki airfield. The security service of Ukraine and the Navy conducted a special operation in temporarily occupied Crimea on the night of the 21st of September inflicting a powerful drone strike on Saki airfield. The sources in the security service of Ukraine said this to Ukraine's Kupravda media outlet. The sources said that the special services used drones to overload Russian air defenses and then launched Neptune missiles. At least 12 combat aircraft including Su-24s and Su-30s as well as a Pantsia anti-air missile system were at the airport. There was also a training base for Mohaja UAV operators. These drones are used by the Russians to coordinate their own air attacks and sometimes deployed as a strike drone. The sources said the strikes by the security service of Ukraine and the Navy hit their targets and caused serious damage to the Russian equipment. The security service of Ukraine reported that Russian personnel were killed and expensive military systems were destroyed as a result of an attack on a command post of the Russian Black Sea Fleet near Sevastopol on the morning of the 20th of September. The Russian generals have designated their base as their backup command post so that they could not be targeted at the main place of deployment. Now not only Russia's manpower is affected but also the expensive military systems that were located at this base. Security service of Ukraine said. Earlier the Russian Ministry of Defense and Russian news outlets reported explosions in occupied Crimea and the invaders claimed to have shot down 19 drones over the peninsula.
