Reinforced Russian troops backed by airstrikes pummeled a portion of eastern Ukraine on Saturday, blowing up bridges and shelling apartment buildings as they fought to capture two cities that would put a contested province under Moscow's control, Ukrainian officials said.
Russian and Ukrainian forces battled street-by-street in Sievierodonetsk and neighboring Lysychansk, regional governor Serhiy Haidai said. Russian strikes killed four people, including a mother and child, in the nearby village of Hirske, Haidai said.
