On the seventh and eighth days of fighting Russian forces take the Black Sea port of Kherson in southern Ukraine, the first major city to fall after a string of setbacks for Moscow. They also pound the besieged port city of Mariupol, which is without water or power. Thirty three people die after Russian forces hit residential areas, including schools, in the northern Ukrainian city of Chernihiv, the local governor says. UNHCR estimates 1 million people have now fled the war in Ukraine as Russia says 498 of its troops have been killed in Ukraine, its first official death toll since President Vladimir Putin launched his invasion a week ago.
