We link up with the BBC World Service... On the 13th day of the Russian invasion into Ukraine we collaborate with the Global News Podcast to answer your questions. Jackie Leonard (from the GNP), alongside Gabriel Gatehouse and Vitaliy Shevchenko (from UC), guide us through questions about the historical context of the war, the nuclear threat, and the information war. BBC Chief International correspondent, Lyse Doucet, joins us from Kyiv, to explain what could happen if Ukraine doesn't manage to hold the capital. And BBC Diplomatic Correspondent, James Landale, comes on to explain what impact the Western sanctions are having on Russia. This episode of Ukrainecast x Global News Podcast was made by Phil Marzouk. The studio director was Gareth Jones. The assistant editor was Sam Bonham.
