Authorities say Russian drones have slammed into two Ukrainian cities, killing at least one person in nighttime attacks.

The Russians attacked Ukraine with 280 aerial targets on the night of 20-21 June. Strikes were recorded in the city of Kremenchuk, Poltava Oblast, and debris of downed targets fell in three locations.

Russia's overnight drone assault targeted the southern Ukraine port city of Odesa and the northeastern city of Kharkiv, hitting apartment blocks, officials said. The barrage of more than 20 drones injured almost two dozen civilians, including girls aged 12 and 17, Ukrainian President Volodymyr Zelenskyy said.
