10 days that changed the world

Victoria catches up with Fergal Keane, who is in Lviv in the West of Ukraine, where thousands of refugees are at the station trying to get out of the country.

Despite a planned ceasefire in two southern cities, Fergal explains why evacuations had to be halted because of continued Russian shelling.

They are joined by Kevin Connolly, former BBC correspondent in Moscow and Patricia Lewis, Director of the International Security programme at Chatham House. Together they discuss comparisons with the Cold War, the ongoing nuclear threat and if a no-fly zone could ever work.

Today’s Ukrainecast was made by Estelle Doyle and Alix Pickles. The studio director was Jonny Baker. The editor is Jonathan Aspinwall.
