A Russian missile attack has struck a district police department in the city of Kryvyi Rih in Dnipropetrovsk Oblast, Governor Serhii Lysak reported on Sept. 27.
At least four men were injured, Lysak said. More people may be trapped under the rubble.
"The fate of four people is currently unknown," the governor said.
Search and rescue operations at the site of the strike are ongoing.
An explosion was reported in Kryvyi Rih almost immediately after an air raid alert went off.
Kryvyi Rih, with a population of around 660,000, is the second most populous city in Dnipropetrovsk Oblast.
It has suffered multiple deadly attacks by Russian forces since the outbreak of the full-scale war.
At least 53 people were injured in the Russian missile attack on Kryvyi Rih on July 8. The strike also killed 10 people, local authorities said.
