KIEV, June 3 (Xinhua) -- Ukrainian President Volodymyr Zelensky said on Wednesday that Ukrainian forces had struck Russia's St. Petersburg Oil Terminal overnight.

"The distance from Ukraine's state border to this facility of Russia's oil industry, which serves the war, is about 1,100 kilometers," Zelensky wrote on X.

He said Ukrainian forces also hit "pure military targets" at the Kronstadt naval base, as well as a facility in Russia's Tambov region involved in weapons production.
