Ukraine Sinks Russian Sub Amid Escalating Assaults

Ukraine claims to have sunk the Russian submarine Rostov-on-Don in Crimea's Sevastopol port, marking a significant blow to Russia's Black Sea Fleet, and reportedly damaged four Russian S-400 air defense systems. Russian officials have not confirmed the submarine's sinking. This event is part of a larger pattern of Ukrainian assaults on Russian naval assets in Crimea. Concurrently, Russia has reportedly destroyed two U.S.-made Patriot air defense systems in Ukraine's Odesa region, as part of its ongoing efforts to degrade Ukrainian defenses. These developments highlight the escalating military engagements between the two nations.
