ZAPORIZHZHIA, Ukraine (AP) – Russian forces have unleashed artillery fire on towns in eastern Ukraine, killing and wounding dozens of civilians, and began storming the bombed-out steel mill in Mariupol. Scores of people were evacuated from the steelworks after enduring weeks of shelling against the city’s last pocket of resistance. The governor of the eastern Donetsk region says Russian attacks left 21 dead on Tuesday, the highest number of fatalities in almost a month. Thanks to the evacuation effort over the weekend, 101 people emerged from the bunkers under Mariupol’s Azovstal steelworks. U.N. and Ukrainian officials are hoping to organize more evacuations if the security situation allows it. The EU leader meanwhile called on the 27-nation bloc to ban Russian oil imports.
