The full horror of Mariupol - a BBC investigation

We hear from BBC Panorama reporter Hilary Anderson about her documentary on the devastating siege of Mariupol. She travelled over 3,000 miles through Ukraine and Europe hearing survivors’ stories and retrieving the wiped phone footage from witnesses to the city’s tragedy.

Also - for months Natalia was unaware of her husband's fate: a Ukrainian soldier, he was captured and made prisoner by Russian forces after the siege of Azovstal in Mariupol. But then she received a phone call. She tells Victoria and Vitaliy what happened next and how hope for a future family together gave them both the strength not to give up.

And as power cuts become more severe across the country, we get the latest from the BBC’s Ukraine correspondent James Waterhouse on the possible full evacuation of Kyiv if there is a total loss of power.

Today’s episode was presented by Victoria Derbyshire and Vitaly Shevchenko.

The series producer is Estelle Doyle. The producers: Arsenii Sokolov, Clare Williamson and Luke Radcliff. The technical director: Gareth Jones. And the editor: Jonathan Aspinwall.
