The Security Service also carried out a precise strike on a military airfield in Rostov – the damage to an An-12, two An-26s, and three helicopters has been confirmed. There have also been good results in the Black Sea."

Specifically, the Rostov-on-Don (Tsentralnyi) airfield in Russia's Rostov Oblast was struck. A fire was recorded, followed by detonation at the facility. In addition, the destruction of two An-26 transport aircraft, one An-12 transport aircraft and three helicopters has been confirmed.
The Slavneft-YANOS oil refinery in Russia's Yaroslavl Oblast was also struck: a hit and fire were reported at the primary oil distillation unit.
For reference: Slavneft-YANOS is one of Russia's largest oil refining companies and is part of Slavneft PJSC. Its capacity is around 15 million tonnes of oil per year. The plant carries out a full cycle of oil refining and produces motor petrol, diesel, aviation fuel, fuel oil, bitumen and other petroleum products.
The plant supports the needs of Russia's armed forces.
Background: Drones attacked several areas in Russia on the night of 16-17 September. A military air base in Rostov-on-Don and an oil refinery in Yaroslavl may have been among the targets.
