Ukrainian Deputy Prime Minister Iryna Vereshchuk said on Tuesday at least 100,000 civilians wanted to escape from Mariupol in southern Ukraine but could not because of a lack of safe corridors out of the besieged port city.
She said shelling by Russian forces was also preventing rescue workers from accessing the site of a bombed theatre in Mariupol where city officials say hundreds were believed to be sheltering underground when it was hit by an air strike last week.
