Deadly Russian missile strikes hit city north of Kyiv
The acting mayor said at least five people had been killed in the attack.
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 Oleksandr Lomako said Russian missiles had targeted an eight-storey building which he described as social infrastructure in a densely populated area.
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.
