Ukrainians return from abroad to fight Russian invasion

While hundreds of thousands of refugees are leaving Ukraine amid Russia’s armed attack on the country, some Ukrainian men and women are returning home from across Europe to help defend their homeland

MEDYKA, Poland -- While hundreds of thousands of Ukrainians flee their country, some Ukrainian men and women are returning home from across Europe to help defend their homeland in the face of Russia's invasion.

Poland’s Border Guard said Sunday that some 22,000 people have crossed into Ukraine since Thursday, when Russia invaded the country.

At the checkpoint in Medyka, in southeastern Poland, many stood in a line early Sunday to cross into Ukraine.

"We have to defend our homeland. Who else if not us?” said a moustachioed man in front of a group of some 20 Ukrainian truck drivers walking to the checkpoint to enter Ukraine. They came from across Europe to return to Ukraine.
