Grim signs of potential war crimes on the road to Kyiv. The BBC’s Jeremy Bowen joins us from near Ukraine’s capital, where he has seen the burnt remains of civilians, shot dead as they tried to flee Russian soldiers. We also discuss reports of a Ukrainian attack on an oil depot in Russia and the latest plan to evacuate residents of occupied Mariupol. Fergal Keane discusses the trauma many in Ukraine will be left with, long after the fighting stops, and introduces us to Valeriy, who was first evacuated from the Chernobyl nuclear plant disaster in 1986, and now for a second time as a result of the war. And we talk about Vladimir Putin’s ploy to demand oil and gas payments in roubles with political risk and geopolitics expert Dr Otilia Dhand. This episode of Ukrainecast was made by Daniel Wittenberg with Chris Flynn, Phil Marzouk and Miranda Slade. The technical producer was Emma Crowe. The editor is Jonathan Aspinwall.
