According to CNBC, Ukraine’s military general staff said Monday that Ukrainian drones struck a major oil refinery in Omsk in western Siberia, causing a fire at a facility it said is nearly 2,500 kilometers (1,553 miles) from Ukrainian territory and near Russia’s border with Kazakhstan; local Russian officials confirmed the attack and Omsk regional governor Vitaly Khotsenko said emergency services were working at the scene with no casualties reported. Ukrainian President Volodymyr Zelenskyy said “upgraded Fire Point drones” reached the Omsk refinery and called it a blow to Russia’s oil economy, while Ukraine’s military said the Omsk refinery is the largest of Russia’s 11 gasoline producers to be hit by Ukrainian forces and estimated its refining capacity at more than 21 million metric tons of crude oil per year. CNBC also reported that Zelenskyy said Ukraine struck oil facilities in Russia’s Yaroslavl region, and that Russia launched missiles and drones against Kyiv early Monday, killing at least 19 people, while U.S. President Donald Trump said after separate weekend calls with Russian President Vladimir Putin and Zelenskyy that a resolution to the conflict is “getting closer than people realize,” ahead of a NATO summit in Ankara.
