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

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.

One person was killed and at least 14 were injured when Russian drones attacked the Ukrainian Black Sea city of Odesa overnight, damaging high-rise buildings and railway infrastructure, local authorities and prosecutors said on Friday.
