Nearly 9 million people have left Ukraine since Vladimir Putin invaded, the UN refugee agency has said, as the governor of Donetsk called on civilians still in the region to flee.

With Russia stepping up its offensive in the east of the country, there are increasingly loud calls from the Ukrainian authorities for people to escape while they can from frontline areas.
