Ukrainecast

As violence looks set to escalate in Kyiv, Victoria, Gabriel and Vitaliy talk through how the conflict is unfolding across Ukraine.

Dr Andrey Vysotskyi from Okhmatdyt Children’s Hospital in Kyiv describes how two children were brought in with injuries today sustained in an air strike which killed their mum, while children with cancer are being cared for in the basement.

Newsnight’s diplomatic editor Mark Urban joins us to explain what the convoy approaching Kyiv tells us about Putin's latest military strategy.

As fighting continues in Ukraine, Victoria Derbyshire and Gabriel Gatehouse look at how the crisis is being reflected in Russia. They’re joined by Angus Roxburgh, who spent three years as a consultant to the Kremlin, to discuss whether the people closest to Putin will stay loyal to him though this conflict. And the BBC’s Liza Fokht in Moscow has been asking Russians what they think about the invasion.

Putin moves Russia's nuclear forces to "special alert”, in response to what he described as “aggression” from Nato countries. Meanwhile as fighting continues in the streets across Ukraine’s biggest cities, President Zelensky says his delegation will meet with Russia at the Belarus border for talks.

Is President Putin using his nuclear arsenal as a conflict deterrent or as a threat to the West? Victoria and Gabriel are joined by the director of the International Security Programme at Chatham House, Dr Patricia Lewis.

And as hundreds of thousands flee Ukraine, we hear from Newsnight’s Lewis Goodall from the border in Poland, where he’s been speaking to families trying to make their way to safety.

Ukrainians, from Kyiv to the UK, answer calls to defend their country. The capital has come under attack, but the residents and their president remain defiant, and Russian forces have so far failed to break through their resistance.

Maxim Karaush was at home with family when their apartment building in Kyiv was hit by a missile. He tells Victoria and Gabriel why, after his wife and son were injured and his home destroyed, he asked to speak to us.

We aim to explain a fast-moving conflict and answer your questions about the war. Vitaly is with us again too, and he's been following a group of Ukrainian men in England as they prepare to return to fight for their homeland.
