Ukraine’s President Volodymyr Zelensky stated Sunday that Ukrainian attacks inside Russian territory are producing ongoing gains, citing strikes that have reached as far as the Ural region and targeted oil and fuel infrastructure. He made the comment during an evening address in which he also insisted that fighting continues for the eastern town of Kostyantynivka, rejecting Moscow’s claim to have captured it. Zelensky warned that Russia is preparing a fresh large-scale assault ahead of this week’s NATO summit in Turkey, where he is scheduled to meet US President Donald Trump. The war, now in its fourth year, has seen Kyiv increase cross-border operations, disrupting daily life in Russia, while Russian strikes on Ukraine killed at least four people on Sunday.
