A Russian drone attack killed at least four people and wounded 21 in the eastern Ukrainian city of Dnipro, damaging high-rise buildings and triggering fires in a hotel, service stations and homes, an official said on Saturday.
Both Russia and Ukraine have stepped up their aerial attacks even as US President Donald Trump pushes the Kremlin and Kiev to agree to a ceasefire after more than three years of costly fighting.
Late Friday, Russia sent "more than two dozen drones" to Dnipro, governor of Dnipropetrovsk region Sergiy Lysak wrote on his official Telegram account.
Lysak said four people were killed, and by Saturday morning, he sent an updated statement that said the number of wounded had risen to 21.
"The massive attack caused large-scale destruction and fires. A hotel and restaurant complex, 11 private houses, garages, and a service station were on fire," he said, adding that high-rises and cars were also damaged.
The fires were extinguished, Lysak said, offering condolences to the families of the victims.

Russia and Ukraine earlier accused each other of attacking a Russian gas metering station in Russia's western Kursk region, an important facility via which Moscow used to pump its gas to Europe by pipeline until the end of last year.
Russia captures settlement in Donetsk
Meanwhile, the Russian defence ministry has said that Russian forces have captured the settlement of Panteleimonivka in Ukraine's eastern Donetsk region and Scherbaky in Ukraine's Zaporizhzhia region, according to Interfax news agency.
On Friday, Russian President Vladimir Putin called for a "transitional administration" to be put in place in Ukraine and vowed his army would "finish off" Ukrainian troops.
Ukrainian President Volodymyr Zelenskyy dismissed Putin's call for a UN-run administration as the Russian leader's latest ploy to delay a peace deal.
French President Emmanuel Macron confirms that not all allies agree, but he emphasises that unanimity is not required.
