UN agency says more than 3 million Ukrainians have fled the country since Russia launched its attack

• Over 3 million Ukrainians have fled the country since Russia launched its attack on February 24.
• The UN's International Organization for Migration confirmed the figure on Tuesday.

More than 3 million Ukrainians have fled the eastern European country since Russia launched its attack on February 24, the United Nations announced on Tuesday.

"3 Million women, children and vulnerable people separated from their loved ones," António Vitorino, chief of the UN's International Organization for Migration, said in a statement on Twitter. "We need an immediate cessation of hostilities."

On Monday, the UN's Refugee Agency estimated that at least 2 million more people were displaced within Ukraine.

The Refugee Agency has projected that 4 million people may be displaced in neighboring countries, and 6.7 million people could be displaced within Ukraine as a result of the conflict.

Most refugees have so far fled to Slovakia, Romania, Hungary, Moldova, and Poland, which has taken in the majority of Ukrainians.

Russian forces have continued their assault on the Ukrainian military, and civilians, leading to concerns from the international community that there have been possible human rights violations and war crimes.
