Israel carries out extensive airstrikes in Gaza

Hamas officials say more than four hundred people have been killed. Does this mean that the ceasefire between Israel and Hamas is over?

Also on the programme: President Trump and President Putin are to have a phone call to discuss a potential ceasefire in Ukraine. We discuss the historical parallels of this occasion; and the legendary jazz musician Herbie Hancock is one of the winners of the Polar Prize, the nearest thing that music has to a Nobel prize. He talks about his life and his extraordinary career.
