A Russian attack that set ablaze a holiday camp in central Ukraine killed two people and wounded another dozen, local authorities said.
Governor Ivan Fedorov said Russian forces carried out 567 attacks over the 24 hours into this morning across 16 settlements in the Zaporizhzhia region.
Emergency services posted images showing firefighters putting out flames in single-storey cottages.
"There's no military sense in this attack. It's just cruelty to scare people," President Volodymyr Zelensky said on social media, adding that hundreds had been left without electricity after Russian attacks further south.
Zaporizhzhia has been on the front lines of the war that Russia launched against its smaller neighbour in February 2022.
At least nine buildings were damaged in the early morning strikes on the Zaporizhzhia city district alone, Mr Fedorov said on the Telegram messaging app.
Zaporizhzhia city is the administrative centre of the broader region.
"Emergency services continue to respond on the ground," Mr Fedorov said.
Both sides deny targeting civilians in their strikes on each other's territory. But thousands of civilians have died in the conflict, the vast majority of them Ukrainian.
Meanwhile, US special envoy Steve Witkoff has arrived in Moscow and was greeted by Russia's investment envoy Kirill Dmitriev, a source has said.
