The FSB of the Russian Federation has arrested a Ukrainian sleeper agent in Volgograd. This agent was ordered by his superiors to install a navigation module for communication relay for suicide drones near the Engels Air Base, but he had already been under surveillance by the FSB of the Russian Federation.
Engels Air Base is an important base for the Russian Aerospace Forces' strategic bombers. Many Russian strategic bombers need to refuel and arm here before taking off, so this place has become a key target for the Ukrainian forces.
