UN says the war could lead to long-term famines. Victoria and Vitaliy hear about what's going on by speaking to Sergey, a farmer from southern Ukraine, and the UN’s Pierre Vauthier. And, after weeks of worry, we check-in with Nataliya, who tells us that her husband, who was fighting at the Mariupol steelworks, is alive and is now being held in Russian-controlled territory. Today’s Ukrainecast was made by Estelle Doyle with Phil Marzouk and Alix Pickles. The technical producer was Emma Crowe. The assistant editor was Sam Bonham.
