People disembark a train at a metro station in Kyiv. Millions of refugees have left Ukraine in the past few weeks.

The influx of Ukrainian refugees into Poland and other border countries could soon be on a “different scale”, aid agencies have said, as the western city of Lviv faces escalating Russian attacks.

David Burns, from Irish aid agency Goal, said with each attack near the border region, there is a “big surge” in terms of numbers heading to cross the border.
