Flames engulfed a university building's wooden roof in Donetsk following Ukrainian shelling on Saturday, said an emergency official in the Russia-controlled city in eastern Ukraine. "As a result of the latest attack on Donetsk, the first building of the University of Economics and Trade is on fire," Alexei Kulemzin, the Russia-installed mayor, said on Telegram. "We are using 12 water tanks, three ladders and 100 fire fighters," said Alexei Kostrubitsky, the Russia-installed emergency minister for the region that Moscow calls the Donetsk People's Republic.
