Ukrainian drones flew all the way to Siberia to strike Russia's largest oil refinery

Ukraine struck Russia’s largest oil refinery, located in the city of Omsk, on Monday, marking what its forces say was its furthest-ever drone attack in the war. The Omsk facility, which processes about 21 million tons of oil a year, is in Western Siberia and about 1,700 miles from Ukrainian territory — roughly the distance between Los Angeles and Houston.
