Since Russia invaded Ukraine more than two years ago, about 6.5 million Ukrainians have left the country. One of them is 10-year-old Artem Fedorenko, who lost part of his arm in a Russian bombing that killed his father and brother. Today, he and his mother Oksana are rebuilding their lives in suburban Minneapolis with help from the Minnesota-based Protez Foundation. MPR News brings us their story.
