Ukraine said one of its missiles had caused the Moskva to sink, a powerful symbol of its resistance to a better-armed enemy. Moscow said the ship sank while being towed into a stormy sea following a fire caused by an ammunition explosion and that more than 500 sailors were evacuated. The United States believes Moscow has been hit by two Ukrainian missiles and that there have been Russian casualties, although the numbers are unclear, a senior US official has said. None of the ratings could be verified independently. The Ukrainian military said on Saturday that the presence of Russian warships in the Black Sea, armed with naval missiles, suggested that Russia was more likely to use them to strike at Ukraine’s defense industry and logistics infrastructure.

Home to 400,000 people before the invasion of Russia, Mariupol has been reduced to rubble.

Russia initially described its targets in Ukraine as “a special military operation” to disarm its neighbor and defeat the nationalists there. After ousting its invading force from the outskirts of Kiev this month, Moscow said its main military goal was to occupy Donbass, the eastern part of the country controlled by Russian-backed separatists since 2014. Kyiv and its Western allies say these are false excuses for an unprovoked offensive war that has driven a quarter of Ukraine’s 44 million people home and killed thousands.
