President Putin fired an experimental hypersonic missile at Dnipro - one of Ukraine’s biggest cities - and has talked about the nuclear option again. On the frontline, Ukraine appears to be losing ground by the day - in this episode of The Political Fourcast, we talk about how the Ukraine-Russia war is escalating.

Krishnan Guru-Murthy is joined by Dr Hanna Shelest, Director of Security Programmes at the Ukrainian think tank Ukrainian Prism, and Channel 4 News international editor, Lindsey Hilsum, who is currently in Dnipro in eastern Ukraine.

Produced by Silvia Maresca and Girish Juneja.
