Civilian evacuations from the beleaguered city of Mariupol are expected to resume at 7 a.m. local time Tuesday, city officials said. Some 200 civilians, including about 20 children, remain trapped in a steel plant in the city that Russia has resumed shelling, according to a local police chief. There was little detail on when a convoy of civilians that had already left the plant, escorted by international officials, would make it to Ukrainian-held territory.
