Ukraine managed to hit Russia's largest oil refinery, which also appears to be one of the country's deepest strikes inside the country, Kyiv said.
Ukraine's military general staff said the strike caused a fire in the facility, located in the cityof Omsk, which is more than 1,500 miles from its territory and near the border with Kazakhstan. It is estimated to have the capability to refine more than 21 million metric tons of crude oil per year, according to CNBC.
