A Ukrainian missile struck the headquarters of Russia's navy in Crimea. The Russian Defense Ministry initially said one servicemember was killed in the Friday attack, but then issued a statement saying he was missing. Images posted on social media showed plumes of smoke over the Black Sea Fleet headquarters in the city of Sevastopol. Russia said five missiles were shot down by its air defense systems responding to the attack. The attack comes a day after Russian missiles and artillery pounded cities across Ukraine, killing at least five people. Military experts say it is essential for Ukraine to keep up its attacks on targets in Crimea to degrade Russian morale.
