‘Russian jets bombed an art school where about 400 Ukrainians were sheltering in the besieged eastern port city of Mariupol on Sunday. Mariupol Mayor Vadym Boychenko said “no information” was immediately available on casualties or how many people were trapped in the rubble of Art School No. 12. The bombing came as Russian forces pushed into all of the city’s civilian neighborhoods, resulting in house-to-house warfare as Russia and Ukraine fought for control and Ukraine refused Russia’s call to surrender the city. The escalating battle for Mariupol came as Russia’s advance stalled in Kyiv and other cities.’ Washington Post, 21 March
