The regional governor reported that Russian airstrikes on the badly battered Ukrainian city of Mykolaiv on the country's southern frontline killed five people and wounded seven others on Friday.

"Today, they fired at another location near a public transportation stop," Vitaliy Kim claimed in a social media post.

Initially, he reported that four people had been murdered in the attack, but he then said five people had been killed and seven injured, with emergency agencies on the site.

Mykolaiv, a city near the Black Sea, has been bombarded daily for weeks and lost about half its estimated pre-war population of nearly 500,000 people.

It is the main metropolitan center under Ukrainian control near the frontlines in the Kherson region, where Kyiv's army has launched a counteroffensive to recover possession of the economically and strategically vital coastal zone.

The Ukrainian presidency said on Friday that residential residences were among the structures damaged or destroyed by Russian shelling in Mykolaiv the previous day.

"A delivery point for humanitarian aid was also damaged. Three persons have been injured, the report stated.

In the eastern Donetsk area, governor Pavlo Kyrylenko reported that Moscow's soldiers had murdered eight people and injured nineteen others in raids the day before.
