KYIV - Four people were killed and five were wounded in Russian shelling of Ukraine's southern region of Kherson on Thursday, the regional prosecutors' office and a presidential official said.

The office said on the Telegram messaging app that Russian forces shelled the town of Beryslav, killing a man who was riding a bicycle.

In a separate massive shelling of several settlements in Kherson district, three people - two men and a woman - were killed, it said.

"It is preliminarily known that the shelling was carried out with cluster munitions," Andriy Yermak, the head of Ukraine's presidential office, said on Telegram.

Russian troops abandoned Kherson and the western bank of the Dnipro River late last year, but now regularly shells those areas from positions on the eastern bank.

Reuters could not independently confirm the report.
