Is the Nova Kakhovka dam breach the most significant moment in the war so far?

Thousands of people have been evacuated after a dam in the Russian-occupied Kherson region of Ukraine was breached on Tuesday. International intelligence organisations believe it is most likely the dam was deliberately targeted by Russian forces in an attempt to delay Ukraine’s expected counteroffensive. NATO’s secretary general has said the move demonstrates Russia’s brutality. But Moscow denies being responsible for the damage to the dam. It insists Ukraine is to blame. On the Sky News Daily, Kimberley Leonard is joined by our international correspondent John Sparks, and Sean Bell, military analyst and former Air Vice-Marshal, to discuss the implications of the dam breach for the course of the war.
