In today's On The Line, host Jen Gerson sits down with longtime friend and Calgarian Paul Hughes, who left his comfortable home in Alberta to help in Ukraine at the outbreak of war four years ago. Hughes, who was joined by his son, Mac, has now been a witness to the extraordinary heartbreak and courage of the Ukrainian people. His son was seriously injured; Hughes has been kidnapped by Russians; and he's even now regularly bombarded by sirens and bomb threats. He speaks to Gerson from a darkened apartment in Kharkiv, where the latest assault has left him without electricity or heat. They also talk about what his experience has taught him about the separatist threat brewing back home.
