The regional governor says three of the five children injured on Saturday are in “serious condition.”
Twenty people, including five children, were injured in a Russian airstrike on the central Ukrainian city of Dnipro, officials said.
Dnipropetrovsk regional governor Serhiy Lysak said on Saturday that three of the children were in “serious condition” after the attack on a residential area.
A total of 17 people were treated in hospital, he added on Telegram.
According to media reports, emergency teams had pulled four people out from under the rubble in the area known as Pidhorodnenska.
Lysak said another child was probably still trapped.
Social media reports say a Russian missile caused the explosion and also hit an emergency services building.
There was no confirmation of a missile strike from Ukrainian military officials.
Ukrainian President Volodymyr Zelenskyy, also writing on Telegram, said the explosion occurred between two residential buildings.
“Unfortunately, there are people under the rubble,” Zelensky wrote. “Once again Russia proves that it is a terrorist state.”
Moscow denies that its armed forces attack civilians.
Photos posted to social media showed rescue teams at work inside a shattered, smoldering building amid piles of twisted building materials.
Russian airstrikes over Ukraine have stepped up in recent weeks, as have raids in the opposite direction.
Russian officials on Saturday said Ukrainian shelling killed two people in Belgorod, a border region hit by repeated attacks this week. The latest deaths bring the total toll in Belgorod border villages to seven this week.
Kiev has said for months that it is preparing a major counter-offensive against Moscow’s occupying forces as it seeks to retake land lost since Russia invaded in February 2022.
