The UN refugee agency says more than 4 million people have now fled Ukraine following Russia’s invasion, a new milestone in the largest refugee crisis in Europe since World War II.
The UN High Commissioner for Refugees posted today on a website that tracks refugee flows around the world that 4.01 million people have now fled Ukraine.
Of those, 2.3 million have entered Poland.
Aid workers said the flow has eased in recent days as many people await developments in the war.
An estimated 6.5 million people have also been displaced from their homes within Ukraine.
