KYIV, Ukraine (AP) — Officials say that Russia and Ukraine have traded nighttime drone attacks again. They say Kyiv targeted Moscow and the Kremlin’s forces launched another bombardment of Ukrainian grain storage depots early Wednesday. Those strikes in what have recently become signature strategies of the almost 18-month war. Authorities said a three-hour nighttime Russian drone attack in Ukraine’s southern Odesa region overnight Tuesday caused a blaze at grain facilities. Russian officials claim to have downed Ukrainian drones in Moscow and the region around the capital, though one smashed into a building under construction.
