(Reuters) -Russian troops shelled and bombed the Azovstal steel plant in Ukraine's southern port city of Mariupol on Tuesday, confirming earlier reports of strikes on the encircled plant, where the mayor said more than 200 civilians were still trapped.
According to the RIA news agency, Russia's defence ministry said its forces had started to destroy Ukrainian firing positions established after the defenders "took advantage" of a U.N.-brokered ceasefire that had allowed several groups of civilians to escape the plant in the previous two days.
