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.
The train that crosses Siberia takes 4 days to cross it, running 24 hours a day (with 30 min stops once or twice a day).
