Christiane is in Ukraine this week as the country faces its biggest government shakeup since Russia’s full-scale invasion began over 30 months ago, with the war at a critical turning point. She sits down with Ukraine’s Army Chief, General Oleksandr Syrskyi, for an exclusive interview from an undisclosed location in eastern Ukraine. Foreign Minister Dmytro Kuleba sat down with her in Kyiv to discuss Ukraine's strategic gains and looming challenges just one day before he offered to resign. Then, a look at the cutting-edge land drones Ukraine is using to transform the reality on the battlefield. Plus, Oscar-winning filmmaker Susanne Bier speaks to Christiane her new Netflix hit, “The Perfect Couple”, and working with Nicole Kidman. From Christiane’s archive, we revisit the heartbreaking cost of the war there, with an update on one of Ukraine's war amputees. And finally, commemorating Mother Teresa’s legacy of compassion and care on the anniversary of her death.
