GENEVA, Switzerland (AFP) — More than 3.8 million people have fled Ukraine since Russia’s invasion a month ago, UN figures showed Sunday, but the flow of refugees has slowed down markedly.

The UN refugee agency, UNHCR, said 3,821,049 Ukrainians had fled the country — an increase of 48,450 from Saturday’s figures.

Around 90 per cent of them are women and children, it added.

Of those who have left, 2.2 million have fled for neighbouring Poland, while more than half a million have made it to Romania. Nearly 300,000 have gone to Russia.

Before the crisis began a month ago, EU member Poland was home to around 1.5 million Ukrainians.

In total, more than 10 million people — over a quarter of the population in regions under government control before the February 24 invasion — are now thought to have fled their homes, including nearly 6.5 million who are internally displaced.

Ukraine’s refugee crisis is Europe’s worst since World War II.

The UN children’s agency, UNICEF, said Thursday that 4.3 million children — more than half of Ukraine’s estimated 7.5-million child population — had been forced to leave their homes.

It puts at some 1.5 million the number of those children who have become refugees, while another 2.5 million are displaced inside their war-ravaged country, it said.

The number leaving daily has fallen well below 100,000 per day, and even 50,000 in recent days, even as living conditions in Ukraine worsen.

The figures do not include citizens of neighbouring states who have left Ukraine to return home.
