The attacks almost completely destroyed power plants serving the city of Bakhmut and the nearby town of Soledar, said Pavlo Kyrylenko, the Ukrainian governor of the region. The shelling killed one civilian and wounded three, it said late Saturday. “The destruction is daily, if not hourly,” Kirilenko said in an interview on state television. Moscow-backed separatists controlled parts of Donetsk for nearly eight years before Russia invaded Ukraine in late February. Protecting the self-proclaimed separatist republic was one of Russian President Vladimir Putin’s justifications for the invasion, and his troops have spent months trying to take over the entire province.
