(Reuters) -Russian missile and guided bomb strikes on Ukraine's southern cities of Mykolaiv and Kherson injured at least 25 people, local officials said on Wednesday.

Nineteen people, including one teenager, received injuries when Russia struck Kherson, Roman Mrochko, head of Kherson's military administration, said on Telegram. Three people were in a severe condition.

"The city centre of Kherson. In the middle of the day, three Russian aerial bombs hit a residential area," regional governor Oleksandr Prokudin said on Telegram.

Eight apartment blocks, private houses, two schools, and a medical facility were damaged, local officials said.

Separately, a Russian missile attack caused a heavy fire in a car repair service in Mykolaiv, emergency services said on Telegram. At least six people were wounded.

Russia denies targeting civilians but thousands have been killed and injured in its strikes during the 27-month-old full-scale invasion of Ukraine.
