Sevastopol officials say power restoration will be gradual after overnight Ukrainian drone strikes that left two districts without electricity and injured two people.Authorities reported about 70 Ukrainian drones shot down over Sevastopol while the Russian Defense Ministry said it intercepted 323 drones nationwide and the commander of Ukrainian drone forces, Robert Brovdi, said strikes hit the city’s main power substation.The strikes follow Kyiv operations that damaged a rail bridge near Rozdolne and regional energy assets, worsened fuel shortages that led Moscow-backed authorities to suspend civilian gasoline sales in Crimea and prompted canceled events and heightened security as US-mediated talks remain stalled.
