A Russian missile attack has killed eight people in the city of Chernihiv in northern Ukraine, according to its acting mayor.

Oleksandr Lomako said another 18 people were wounded when Russian missiles hit an eight-storey building in a densely populated area.

Three missiles had struck close to the centre of the city, officials said.

The attack came hours after reports of a Ukrainian attack on a Russian military airfield in occupied Crimea.

Details have yet to be confirmed, although local social media channels shared video of an apparent fire on the airfield at Dzhankoy in northern Crimea.

In Chernihiv, the acting mayor said one building had suffered a direct hit from one of the Russian missiles and several floors had been damaged.

Video from the scene showed people diving for cover at a bus stop in the city. Officials appealed for the public to come forward to give blood.

Chernihiv is only 100km (60 miles) from the Russian border and has seen a number of deadly attacks since the full-scale Russian invasion in 2022. It was occupied for several weeks at the start of the war while Russia tried to capture Kyiv to the south.
