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

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