Drones of the Security Service of Ukraine (SBU) and a Neptune missile struck an ammunition storage depot and reconnaissance drones near the village of Chaltyr on the western outskirts of the Russian city of Rostov-on-Don on the night of January 10, an informed source in the SBU told Interfax-Ukraine.

"The SBU, together with the Ukrainian Navy, hit an extremely important target – a storage with reconnaissance drones correcting enemy strikes on Ukrainian cities and the front line. Now there will be fewer of these Russian ‘birds’ in the sky. Work on military facilities in the enemy's rear will continue," the agency's source said.

According to it, at first the drones put the burden on the Russian air defense, and then the Neptune get into the facility. Subsequently, local residents on social networks discussed multiple explosions near Chaltyr, which indicated a secondary detonation of ammunition.
