More than 2.5 million Ukrainians have fled their country since Russia's invasion

 .

 In the span of just two weeks, millions of Ukrainian refugees have been forced to flee as the brutal Russian invasion of their homeland continues.

The amount of people on the move constitutes "the fastest growing refugee crisis in Europe since World War II," UN Refugee Agency (UNHCR) Commissioner Filippo Grandi said Sunday, and is reminiscent of the 2015 migrant crisis spurred by the war in Syria which resulted in an estimated 1 million asylum-seekers.

While many residents in the central and eastern portions of the country have relocated to western Ukraine and away from the front lines, more than 2.5 million Ukrainians have left entirely following Russia's invasion on February 24, according to the latest United Nations refugee estimates.
