Refugee children are arriving in countries bordering Ukraine and being whisked to safety by volunteers as their parents return to fight the Russian conflict.
The United Nations estimates that up to 4 million people could flee if the fighting escalates.
ITV News reporter Lucy Watson is in Rzeszow, Poland, at a train station about 50 miles from the border with Ukraine, witnessing extraordinary scenes of solidarity as Polish people come to their neighbours' aid.
Volunteers have set up a relief effort at the station, to help feed and care for weary Ukrainians forced to flee across the border.
