A UKRAINIAN attack in south-west Russia killed one person and wounded three more, local officials said today, as Kiev’s forces continued to bombard Russia’s oil facilities.

The head of Russia’s Samara region, Governor Vyacheslav Fedorishchev, said that a child was among the injured. He also said that homes and other residential buildings were damaged in the strike, as well as an unspecified “industrial site.”

Russian media outlets reported that the attack’s target was the region’s Syzran oil refinery, with many sharing images that appeared to show plumes of black smoke rising over the site.

The refinery, which is owned by fossil fuel giant Rosneft and sits about 500 miles east of the border, has been a repeated target for Kiev’s forces.

Russian attacks on Ukraine on Saturday killed four people, including a child, in the north-east Sumy region and two others in the southern region of Odessa.

Eleven people, including one child, were wounded in missile and drone attacks on Kiev that same day.
