San Francisco Frontiers - More than two million flee war in Ukraine: UN

- 2,011,312 refugees -

UNHCR, the UN Refugee Agency, recorded 2,011,312 refugees on its dedicated website, 276,244 more than the previous count on Monday.

UNICEF, the UN children's agency, believes hundreds of thousands of them are youngsters.

Authorities and the UN expect the flow to intensify as the Russian army advances deeper into Ukraine, particularly as it approaches the capital, Kyiv.

Before Russia invaded, more than 37 million people lived in Ukrainian territory under the control of the central government.

Besides those who have left, an unknown number have been displaced from their homes within the country.

The International Organization for Migration said that 103,000 third-country nationals were among those who have fled.

"There are countless tens of thousands of others who remain in the country stranded," IOM spokesman Paul Dillon said, citing a mixture of overseas students and people who have been living or working in the country for years.

He announced a partnership with Airbnb to connect refugees to free or heavily-discounted short-term housing in neighbouring countries, with more than 26,000 hosts having signed up so far.

Here is a breakdown of where Ukrainian refugees are, according to the UN Refugee Agency:

- Poland -

More than half of those who have fled Ukraine are now in Poland, with UNHCR saying on Monday 1,204,403 refugees were now in the country.

The number swelled by 176,800 in 24 hours.

Poland has championed the cause of Ukrainian refugees. The government has set up reception centres and charities have mobilised in a massive aid effort, helped by the estimated 1.5 million Ukrainians already living in the EU member state.

The Polish government on Monday proposed a law making it easier for Ukrainian refugees to stay by allowing Ukrainians to remain in Poland for 18 months and renew their permit for a further 18.

Ukrainians would also be allowed to work and access both healthcare and schools.

- Elsewhere in Europe -

Some 210,239 people have fled Ukraine to other European countries, according to UNHCR.

- Hungary -

Some 191,348 refugees are now in Hungary -- 10 percent of the total who have fled Ukraine. The number was up 11,185 on Monday's figure.

The country has five border crossings with Ukraine and several border towns, including Zahony, have turned public buildings into relief centres, where Hungarian civilians are offering food or assistance.

- Slovakia -

Across Ukraine's shortest border, some 140,745 refugees are now in Slovakia.

- Russia -

UNHCR says the number of refugees who have crossed Ukraine's longest border into Russia since the invasion is 99,300.

UNHCR says that an additional 96,000 people moved to Russia from the separatist eastern Donetsk and Luhansk regions between February 18 and 23, in the days before the Russian invasion.

- Moldova -

Some 82,762 refugees were now in Moldova, according to figures updated to the end of Sunday, though many thousands more have passed through the non-EU state on their way to other countries.

According to the UNHCR, many refugees are continuing on to Romania or Hungary, often to reunite with family.

Prime Minister Natalia Gavrilita said Sunday that more than 230,000 people have crossed the border from Ukraine.

Some 82,062 refugees from Ukraine are now in Romania, according to latest figures dated to the end of Sunday.
