Geneva (AFP) - More than 5.3 million Ukrainians have fled their country since Russia invaded two months ago, the United Nations said Wednesday, with more than 52,000 joining their ranks in the past 24 hours.
In total, 5,317,219 people have fled Ukraine as refugees since February 24, according to the latest data from the UN refugee agency, UNHCR.
That marks an increase of 52,452 over the figure given on Tuesday.
While the outflow has slowed significantly since March, UNHCR has projected that three million more Ukrainians could become refugees by the end of the year.
The exodus has been described as Europe's fastest-growing refugee crisis since World War II, but a leading humanitarian warned Wednesday that even that was an understatement.
Including the 7.7 million people estimated to be displaced within Ukraine, more than 12 million people were displaced in the first eight weeks of the war, he pointed out.
"People talk about since the Second World War, (but) tell me when in the Second World War there were 12 million people displaced in eight weeks," Jan Egeland, Secretary General of the Norwegian Refugee Council (NRC), told reporters.
The large displacements back then happened "over a longer period," he said.
In addition to the Ukrainian refugees, the UN's International Organization for Migration (IOM) said an additional 224,975 citizens of third countries -- largely students and migrant workers -- have also escaped to neighbouring countries since the invasion began.
Women and children account for 90 percent of the Ukrainians who have fled abroad, with men aged 18 to 60 eligible for military call-up unable to leave.
Almost two-thirds of Ukrainian children have fled their homes.
Before the invasion, Ukraine had a population of 37 million in the regions under government control, excluding Russia-annexed Crimea and the pro-Russian separatist-controlled regions in the east.
Here is a breakdown of how many Ukrainian refugees have fled to neighbouring countries, according to UNHCR:
Poland
Nearly six out of 10 Ukrainian refugees -- 2,944,164 so far -- have crossed into Poland, according to UNHCR numbers up to April 26.
Many of them have travelled on to other states in Europe's Schengen open-borders zone.
Meanwhile, more than 800,000 people have crossed from Poland into Ukraine, Polish border guards said.
Before the war, Poland was home to around 1.5 million Ukrainians, chiefly migrant workers.
Romania
A total of 793,420 Ukrainians have entered the EU member state as of April 26, including a large number who crossed over from Moldova, wedged between Romania and Ukraine.
The vast majority are thought to have gone on to other countries.
Russia
Another 627,512 refugees have sought shelter in Russia, according to data last updated on April 26.
In addition, 105,000 people crossed into Russia from the separatist-held pro-Russian regions of Donetsk and Lugansk in eastern Ukraine between February 18 and 23.
Hungary
A total of 502,142 Ukrainians had entered Hungary as of April 26.
Moldova
The Moldovan border is the closest to the major port city of Odessa. A total of 437,362 Ukrainians have crossed into the non-EU state, one of the poorest in Europe, with a population of 2.6 million.Most have moved on.
Slovakia
A total of 360,458 people had crossed Ukraine's shortest border into Slovakia as of April 26.
Belarus
Another 24,719 refugees made it north to Russia's close ally Belarus as of April 26.
Returns
At the same time, many Ukrainians have also travelled back into Ukraine.UNHCR said that between February 28 and April 26, Ukrainian border guards had registered 1,209,500 Ukrainians returning to the country.
UNHCR stressed though that "this figure reflects cross-border movements, which can be pendular, and does not necessarily indicate sustainable returns as the situation across Ukraine remains highly volatile and unpredictable."
