Ukrainian forces hit five Russian refineries in recent weeks, halting two

The targeted facilities include the Ryazan, Ilsky, Saratov, Orsk and Volgograd refineries, Kovalenko said. The Ryazan and Volgograd plants were forced to suspend work following the attacks.

On Nov. 11, long-range drones from Ukraine's SBU Security Service’s Special Operations Center hit the Orsknefteorgsintez refinery in Orsk, Orenburg Oblast — about 1,400 kilometers from Ukraine.

On Nov. 14, Defense Forces struck a refinery in Saratov Oblast and a fuel depot near Engels.

The General Staff of Ukraine's Armed Forces confirmed a hit on the Ryazan refinery on Nov. 15. It is one of Russia's key producers of TS-1 aviation fuel.

Reuters reported in November that the Saratov, Ryazan and Volgograd refineries had halted operations.
