Russian ballistic missiles hit Kyiv early Sunday, wounding three and setting fires, while later attacks on Kharkiv and Zaporizhzhia killed two more people and injured at least 12.
Ukrainian drones also struck Russian-occupied Horlivka, killing four civilians, as Moscow said its air defenses destroyed 133 drones over Russia, Crimea and the Black Sea overnight.
The exchange follows Ukraine's recent drone campaign inside Russia, which the report says has slowed Russian advances and strained fuel supplies, prompting a sharper cycle of retaliatory strikes.
Romania, a NATO member bordering Ukraine, said it shot down another suspected Russian drone over the Black Sea — the third airspace incursion in three days.
