KYIV, Ukraine (AP) — Kyiv’s mayor says that 70% of the Ukrainian capital has been left without power after Moscow unleashed yet another devastating missile barrage on Ukraine’s energy infrastructure. The mayor said Thursday that engineers were doing their best to get electricity back as soon as possible. He said the water supply has been restored in about half of Kyiv on the left bank of the Dnieper River. A punishing barrage of Russian strikes on Ukrainian infrastructure caused power outages across large parts of the country, piling more damage onto Ukraine’s already battered power network and adding to the misery for civilians as winter begins. Russia’s strikes come as its forces have suffered battlefield setbacks in the war that it launched nine months ago.
