President Volodymyr Zelenskyy said Ukraine's military intelligence has evidence that a major oil refinery in Kstovo, Nizhny Novgorod Oblast, has shut down following Ukrainian drone strikes, citing a briefing from HUR chief Oleh Ivashchenko. He said certain categories of Russian exports fell 80% in August alone, calling the losses tangible for both federal and regional Russian budgets.
Zelenskyy also said Russia's own acknowledgments show its Black Sea Fleet is effectively confined to Novorossiysk, and that strikes on the Kamensky Combine in Rostov Oblast cut into Russia's capacity to produce solid-fuel rocket engines. He said Ukraine now has updated data on Russian ballistic missile production and plans to scale it up.
The Kstovo refinery, Russia's fourth-largest by capacity, has reportedly been struck multiple times since May, with the AVT-6 primary refining unit damaged repeatedly.
