Moscow is pressing for Ukraine's complete demilitarization.Evacuations from Mariupol and other besieged cities proceeded along eight of 10 humanitarian corridors that Ukraine and Russia agreed to on Saturday, Deputy Prime Minister Iryna Vereshchuk said, and officials said a total of 6,623 people left Kyiv and other cities.Vereshchuk said planned humanitarian aid for the southern city of Kherson, which Russia seized early in the war, could not be delivered because the trucks were stopped along the way by Russian troops.Mariupol authorities said Sunday that nearly 40,000 people had left the city in the last week, the vast majority in their own vehicles, despite ongoing air and artillery strikes.The Mariupol city council claimed Saturday that Russian soldiers had forcibly relocated several thousand city residents, mostly women and children, to Russia.
