Russia claims that more than 1,000 Ukrainian marines have surrendered in Mariupol, a development that, if true, would mean Ukraine has lost its first major city since the Russian invasion began, per Reuters. The news comes via Russia's Defense Ministry, which said that 1,026 soldiers from Ukraine's 36th Marine Brigade put up the white flag, including 162 officers. While Ukraine's Defense Ministry conceded that Russian forces were continuing their assault on the port city, a spokesman says there was no information on any surrender. More on the war in Ukraine:
