Could the leak of secret Pentagon documents affect the course of the war in Ukraine? Defence expert Sam de Bendern gives her analysis of the US national security breach and we hear about another Russian dissident facing 25 years in prison for criticising the war. The BBC Ukraine correspondent James Waterhouse has been in Kharkiv to see the de-mining efforts as so-called butterfly bombs continue to injure civilians. And we have an aural treat in the shape of YouTube project: How Does Ukraine Sound? Its producer Yevhen Synelnykov has been collecting unique sounds from cities across Ukraine, such as the sea, factories and churches, and making music from them. Today’s episode is presented by Victoria Derbyshire and Vitaly Shevchenko. The producers were Arsenii Sokolov, Clare Williamson and Luke Radcliff. The technical producer was Philip Bull. The series producer is Fiona Leach. The assistant editor is Alison Gee and the editor is Sam Bonham. Email [email protected] with your questions and comments.
