One million refugees flee Ukraine in first week of war

'Rarely have I seen an exodus as rapid as this one,' the UN refugee chief Filippo Grandi said

One million refugees have fled Ukraine in the week since Russia's invasion, the United Nations said Thursday, warning that unless the onslaught ended immediately, millions more were likely to flee.

"Unless there is an immediate end to the conflict, millions more are likely to be forced to flee Ukraine," he warned.
