Ukrainian forces carried out a drone strike on an oil refinery in the Russian city of Omsk on Monday, hitting the country’s most important fuel production site more than 2,500km from the Russia-Ukraine border.
The Omsk Oil Refinery is Russia’s largest, with a design capacity of around 22 million tonnes of crude oil per year. It produces gasoline, diesel, aviation kerosene and other petroleum products, including fuel used by the Russian military.
