Russian shelling killed three people on Monday and damaged power lines and a gas pipeline in the central Dnipropetrovsk and southern Kherson regions of Ukraine, authorities said.
An elderly woman was killed and a man injured in Russian artillery strike on the town of Nikopol, Dnipropetrovsk's governor said.
"A power line and a gas pipeline were damaged," Serhiy Lysak, the governor, said on Telegram messenger.
On Monday morning, two drivers were killed when Russian forces shelled a private transport company parking lot in Kherson, regional governor Oleksandr Prokudin said.
Regional prosecutors said they had opened a war crimes investigation into the artillery strike, which occurred at around 9 a.m. and injured one other person.
Russian forces have regularly shelled Kherson from across the Dnipro River since the regional capital was deoccupied by Ukrainian troops last November.
Ukraine said last week it had secured a foothold on the eastern bank of the Dnipro and that its troops were trying to push Russian forces further back.
