Water supplies returned to residents of Ukraine’s capital on Saturday, and the metro system resumed, Kyiv Mayor Vitali Klitschko said, as the city began to recover from a barrage of Russian missile strikes Friday that pummeled critical infrastructure. A third of people in Kyiv remained without energy, and emergency power shutdowns were scheduled, he added. Damaged cities — including Kharkiv, Sumy, Poltava and Dnipro — reported power outages after the strikes.
