The Omsk Oil Refinery, Russia’s largest oil refinery, has been under attack by Ukrainian strike drones for several hours.

Analysts at Exilenova+ recorded the first explosions at approximately 1:30 p.m. Kyiv time.

“The Omsk Oil Refinery has been under attack for the seventh hour. Explosions are still being heard in the city,” Exilenova+ reported.

A large fire broke out in the industrial zone and continues to spread.

Meanwhile, incidents have been recorded in which Russian air defense missiles flew toward residential buildings.

Ukrainian strike drones traveled approximately 3,000 kilometers to hit the Omsk Oil Refinery, Russia’s largest refinery by capacity.

The facility is part of Gazprom Neft and has a design refining capacity of more than 21 million metric tons of crude oil per year. This accounts for approximately 10% of Russia’s total oil refining capacity.

The refinery specializes in producing AI-92, AI-95 and G-Drive 100 gasoline, Euro-5 diesel fuel, aviation kerosene, lubricants and a wide range of petrochemical products. The facility also helps meet the needs of Russia’s occupation forces.

The refinery has already been targeted in July and October this year. Following the July strike, the facility was forced to suspend oil refining after key equipment was damaged.
