A volunteer carries a child of Ukrainian citizens as they arrive with buses in Przemsyl, eastern Poland, from the Medyka pedestrian border crossing as they flee the conflict in their country following Russia's invasion of Ukraine, in the late hours of February 25, 2022. The UN said more than 50,000 Ukrainians had fled the country in the past two days, calling for "safe unimpeded access" for aid operations. Streams of people in cars and on foot were seen crossing into Hungary, Poland and Romania while hundreds camped out in a train station in the Polish border city of Przemysl.
