KYIV—Russian forces swarmed into the eastern Ukrainian city of Sievierodonetsk, a Ukrainian official said on Monday.
Pro-Moscow separatists claimed the last bridge out of Sievierodonetsk had been destroyed and Ukrainian defenders there must now surrender or die. Ukraine said there was still another way out although it was severely damaged.
Regional governor Sergei Gadai said fighting was raging and Ukrainian forces were defending building by building.
Russian forces now controlled about 70 percent of Sievierodonetsk, he said, and were destroying it “quarter by quarter” in one of the bloodiest assaults since they launched their invasion on Feb. 24.
“Russians continue to storm the city, having a significant advantage in artillery they have somewhat pushed back the Ukrainian soldiers,” Gaidai, who is governor of the Luhansk region that includes Sievierodonetsk, said on Monday….
