Ukrainian refugees fleeing Russia-Ukraine conflicts poured across their country's western borders on Saturday, the third day of fighting, with more than 100,000 reaching Poland so far, many making the final stretch of their journeys to safety on foot.

Axar.az reports that as the fierce fighting intensifies, fearful families thronged European Union borders hoping to enter Poland, Slovakia, Romania and Hungary.

"The numbers and the situation is changing minute by minute," said Joung-ah Ghedini-Williams, a spokeswoman for the UN High Commissioner for Refugees.

"At least 150,000 people have fled, they are refugees outside of Ukraine. At least 100,000 people but probably a much larger number have been displaced inside Ukraine."
