Ukrainian forces have destroyed a strategically important bridge over the Seym River in Russia's Kursk region using U.S.-supplied HIMARS rockets, significantly impacting Russian military logistics and evacuation routes. Ukrainian President Volodymyr Zelenskyy praised his troops for inflicting 'maximum damage' on Russian positions, emphasizing the importance of disrupting enemy logistics. Russian officials, including Kursk Region Interim Governor Alexey Smirnov, confirmed the bridge's destruction and reported civilian evacuation difficulties. The attack marks the largest Ukrainian incursion into Russian territory since World War Two, with Kyiv claiming control over at least 175 square miles. The operation has also exposed the unpreparedness of Russian defenses, which were largely manned by poorly trained conscripts. Both sides continue to report ongoing heavy fighting in the region.
