More than half of the Ukrainians left for Poland, but some of the refugees have already returned home to those regions where the fighting has stopped.
More than 5.5 million people have left Ukraine since the beginning of the Russian invasion, the United Nations Refugee Agency reported on Monday, May 2.
More than three million left for Poland. 825,000 people left for Romania, 681,000 for Russia, 530,000 for Hungary, 447,000 for Moldova, 379,000 for Slovakia, and 25,000 for Belarus.
The statistics are compiled from a variety of sources, mostly from data provided by authorities at official border checkpoints, the agency said.
Earlier it was reported that about a quarter of Ukrainians who left their homes because of the war have already returned.
