At least five people were killed and 52 wounded on Friday when Russian drones attacked a shopping centre in the central Ukrainian city of Kryvyi Rih, local authorities said.
Six children were among the wounded in the daytime attack on President Volodymyr Zelenskiy's hometown, regional governor Oleksandr Hanzha said on the Telegram messaging app.
He posted a photo of black smoke billowing from a large industrial building.
The number of wounded was likely to rise, said Mayor Oleksandr Vilkul, who added the shopping centre had been attacked more than once with a jet-powered drone. NDTV reported.
Russia is escalating its air war on Ukraine as fighting on the battlefield grinds toward the 4-1/2 year mark.
On Thursday, 17 people were killed in a Russian ballistic missile attack on the Ukrainian capital Kyiv.
