KYIV: Ukrainian forces struck Russia’s major Ufa oil refinery for the second time in a week, Ukrainian President Volodymyr Zelensky said Wednesday.

Almost daily long-range attacks on Russian oil facilities have created a fuel crisis and heaped political pressure on the Kremlin as its all-out invasion of Ukraine stretches into its fifth year.

The Ufa refinery is one of Russia’s largest producers of lubricants and is located more than 1,000 kilometers (600 miles) from Ukraine, Zelensky said on social media.

Ukraine also struck a plant producing missile components in Russia’s Penza region southeast of Moscow, some 500 kilometers (300 miles) from Ukraine, Zelensky said.

Russian officials did not confirm the strikes, which could not be independently verified. The Russian Defense Ministry reported intercepting 179 Ukrainian drones over 16 Russian regions, the annexed Crimea and waters of the Azov and the Black Sea.
