A wave of Russian strikes have hammered Ukraine’s energy infrastructure, leaving at least five dead.

We speak to Kharkiv resident Nataliya, who joins us from a special bunker in the city, where officials say 700 000 were left with no electricity.

Also, we hear from one eyewitness who lives next door to one of the targets - Ukraine's largest dam, the DniproHES, which was hit eight times according to Ukrainian officials

And we get the latest from the BBC’s Sarah Rainsford in Kyiv where officials are calling this the largest missile and drone attack on infrastructure of the war so far, and Glen Grant, a military analyst explains the potential strategy behind these strikes.
