Zelenskyy: 'All supplies of components, equipment, and machine tools that Russia uses to manufacture missiles must be completely blocked. And this is also the responsibility of our partners – without foreign components, the Russians are unable to implement a single element of their missile program. The Defense Intelligence of Ukraine also has evidence that operations have stopped at one of Russia’s largest oil refineries in Kstovo, in the Nizhny Novgorod region, which processed 17 million tonnes of oil annually, as well as at other oil refining facilities.'
