The exodus began after the launch of the special military operation by Russia in Donbass, despite the fact that the Kremlin warned that the operation is not directed against civilians.
Some 1.91 million left Ukraine across the border with neighboring Poland, while 429,000 entered Hungary and 228,000 entered Slovakia.
Russia is also one of the main recipients along with Romania and Moldova, according to statistics updated daily by the UNHCR.
The UN dependency also estimated that there are more than two million internally displaced persons in Ukraine and it fears that this figure will triple “soon.”
The current migration crisis is the worst in Europe since the end of the Second World War (1939-1945), according to analysts.
