- Hundreds of Ukrainian refugees crossed the border into Poland on Thursday.
- The country said it would open nine reception centers along its border in anticipation of more arrivals.
Hundreds of Ukrainians have begun crossing the country's western border into neighboring Poland just hours after Russian forces launched an attack on Ukraine early Thursday morning.
Scenes from train stations and bus stops show crowds of travelers donning winter coats and carrying suitcases — many with young children in tow — marking the first wave of what European officials are warning could be an impending refugee crisis.
Ukrainian citizens fleeing the newfound war are flocking to Poland, whose inclusion in both the European Union and NATO offer an extra layer of security and support from military allies throughout Europe.
Fleeing Ukrainians described the hours-long wait to cross the border.

Fleeing refugees told The Wall Street Journal that their journeys to Poland were long and arduous.
At one border post, the outlet reported that multiple buses and minivans were crowded into a parking lot waiting to pick up Ukrainians moving on.
"It's pure chaos here. All our buses are full," a bus driver told the newspaper. "This is just the beginning. People are panicking. Most of our customers are women with children and they are very afraid."
Many are hoping to join relatives already in Poland.

The country is home to more than one million Ukrainians.
Government officials believe another one million Ukrainians could arrive in Poland in the coming weeks.

The welcome centers will offer medical care and food, as well as a gathering place to receive information and updates, Polish officials said, according to Al Jazeera.
Some estimates suggest as many as five million people could be displaced.

Even before Russia launched its assault, Ukraine's defense minister warned that a violent invasion could lead to 3-5 million Ukrainian refugees, while the US posited anywhere from 1 to 5 million people could be displaced, according to the RAND corporation, a nonprofit policy think tank.
Many appeared to be young parents, often with multiple children in tow.
