Officials in Lebanon say almost 500 people have been killed and more than 1,600 injured, after a wave of Israeli airstrikes in the south of the country. It's been the deadliest day of conflict across the border in nearly two decades. We speak to the Lebanese health minister, Firass Abiad, who says thousands of people are fleeing their homes and heading north to escape the bombardment. Also in the programme: We look ahead to Sir Keir Starmer's speech at the Labour Conference in Liverpool; and the tensions over the government's policy towards Israel.
