Ukrainian President Volodymyr Zelensky has renewed his appeal for more long-range weapons and air defences after a missile attack killed seven people including two children.

Axar.az reports that the Russian attack on the town of Vilniansk, near the southeastern city of Zaporizhzhia, also injured 31 others, Ukrainian officials said.

In total, at least 11 civilians were killed and a further 37 wounded in missile attacks across Ukraine on Saturday.

"Our cities and communities suffer daily from such Russian strikes," Mr Zelensky wrote in a post on Telegram.

But he added that there were "ways to overcome this", including "destroying Russian missile launchers, striking with real long-range capability and increasing the number of modern air defence systems".

He posted images from Vilniansk showing a large crater near a smouldering building, as well as several bodies laid out on the ground.
