Ukrainian drones on Monday attacked Russia’s Omsk oil refinery, the country’s largest, damaging an essential part of refinery, the General Staff of the Armed Forces of Ukraine said in a statement.
Videos of a large fire and clouds of smoke billowing from the plant were shared by Ukrainian and Russian social media channels. It was unclear how much damage the refinery had sustained.
The Gazprom-owned oil refinery, located in Siberia, more than 2,500 kilometers (1,550 miles) away from the front line, processes more than 22 million tons of oil per year — around 10 percent of the total oil refined in Russia.
“According to preliminary information, the ELOU-AVT-11 primary oil processing unit with a design capacity of 8.4 million tons of oil per year was hit,” the general staff statement says, referring to partial capacity damage at the refinery. The hit was confirmed by the Ukrainian open-source intelligence project Dnipro. The strike was the farthest Ukrainian drones have penetrated into Russian territory since the war began.
