       Russian forces in Mariupol tried to storm a steel plant housing soldiers and civilians while attempting to crush the last corner of resistance in the city, which holds deep strategic value to Moscow.

       The intensifying attacks on the eve of Orthodox Easter came as Russia claimed it had taken control of several villages elsewhere in the eastern Donbas region.

       While British officials said the Russians hadn’t gained significant new ground, Ukrainian officials announced a nationwide curfew ahead of Easter Sunday, a sign of the war’s disruption and threat to the entire country.
