Video published by a Russia-backed separatist group appears to show an attack on the Azovstal steelworks in Mariupol. The video was released on 4 May but it is unclear when it was filmed.
The commander of Ukrainian forces in the plant says fighting has continued and bombardment has reduced much of the factory to rubble. The Kremlin has denied reports that Moscow’s forces were trying to storm Azovstal.
Hundreds of people have been rescued from Mariupol and negotiations continue to try to evacuate those trapped in the steelworks
