Hungarian Prime Minister Viktor Orbán, Europe's leading anti-migrant politician, affirmed that Hungary was accepting all citizens and legal residents of Ukraine.
"We're letting everyone in," Orbán said.
Nearly 80,000 Ukrainians have crossed into Hungary, according to the border police.
Moldova
More than 70,000 refugees from Ukraine have entered Moldova in the last few days, according to the press service for the Moldovan Interior Ministry on Sunday.
"Last night, 3,423 Ukrainian citizens entered the Republic of Moldova. All border crossings with Ukraine are operating. Increased passenger traffic is observed at the Palanca-Maiaky-Udobne, Tudora-Starokazache and Otaci-Mohyliv-Podilsky checkpoints. At these checkpoints there are many kilometers of queues from the Ukrainian side, the waiting time is ten hours or more," the statement said.
Poland
Poland was one of the first countries that declared its border open to fleeing Ukrainians -- even those without official documents -- and even dropped its requirement to show a negative COVID-19 test.
The Polish government said Saturday that more than 100,000 Ukrainians had crossed the Polish-Ukrainian border in the past 48 hours alone.
Romania
On Saturday, Romania's border post was crowded with Ukrainians, and humanitarian groups set up tents a few miles in, offering food and drink to those arriving.
