Meanwhile, the UN's food agency appealed for entry into Mariupol to deliver food products.
Reports say the city has been low on food, electricity and water for weeks even as the World Food Programme (WFP) has struggled to get safe access to key cities in Ukraine hit by heavy fighting.
WFP said over 7 million people were affected as the result of the war with food delivery to the people almost "broken down in many areas"
