Russia and Ukraine said Friday that attacks had killed several civilians in both countries, as they launched waves of artillery, missile and drone fire at each other.

Kyiv said a Russian drone strike killed two people in the central Ukrainian region of Vinnytsia, and that shelling on the frontline Zaporizhzhia region killed one woman.

At least eight people were killed and 20 others injured on Friday in a Russian strike on the Ukrainian Black Sea port city of Odesa, the regional governor added later.

Russian officials meanwhile said that shelling overnight by Kyiv's army on the Donetsk region killed three children.

Ukrainian shelling of the Russian border region of Belgorod left a member of its territorial defense unit dead, Russian authorities added.
