The UN refugee agency said Wednesday more than 4 million refugees have now fled Ukraine since Russia launched its war in the largest refugee crisis in Europe since World War II.
The new figure was posted on an UNHCR website. More than 2.3 million have arrived in Poland, but many have traveled onward to other countries or back into Ukraine.
Aid workers say the numbers have 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 the country.
More than 608,000 have entered Romania, over 387,000 have gone to Moldova, and about 364,000 have entered Hungary since the war began on Feb. 24, based on counts provided by governments.
From the onset of the war, UNHCR had projected that about 4 million people might flee Ukraine —though it has repeatedly said that it has been reassessing its forecasts.
