Russia's military offensive against Ukraine forced 2.952 million people to leave the country in 19 incomplete days of the war in search of safety, protection and assistance, the Office of the United Nations High Commissioner for Refugees (UNHCR) said as of 13:00 (Kyiv time) on March 14.

The Office said the Ukrainian-Polish border accounted for 60.7% of all refugees.

According to the UNHCR, the number of refugees from Ukraine to Poland since February 24, when Russia started the war, has reached 1.791 million.

Romania received 453,430 people, of which 250,800 people were in transit through Moldova, the department said.

According to it, some 263,890 people arrived in Hungary, some 213,000 in Slovakia, some 86,380 in Moldova.

According to the UNHCR, the flow of refugees from Ukraine to Russia amounted to 142,990, to Belarus (data for March 13) some 1,230.

"As the situation continues to evolve, about 4 million people may leave Ukraine," the UNHCR said.

According to its estimation two days ago, there are now at least 1.85 million internally displaced persons (IDPs) in Ukraine and another 12.65 million directly affected by the war.

UNHCR said that by the middle of 2021 there were 53,470 Ukrainian refugees in the world who applied for the appropriate status, of which 36,490 were in Europe.

As of the middle of 2020, the UNHCR estimated the Ukrainian diaspora in the world at 6.1 million, including 5 million in Europe.

The organization said the right to free movement within the Schengen area means that there are very few border controls in the European Union, so arrivals in Hungary, Poland and Slovakia only reflect border crossings in these countries, however, according to the UN, a large number of people moved to other countries.

In addition, UNHCR does not take into account persons from border countries who leave Ukraine and return home.
