On Background: Israel-Gaza’s tipping point?

Israel's airstrike on a convoy in Gaza earlier this week quickly sparked international condemnation, anger, demands for answers and a lot more pressure on the Netanyahu government over its conduct in this war. The attack on the World Central Kitchen convoy killed seven people, including an Australian aid worker Lalzawmi "Zomi" Frankcom. Joe Biden says he's outraged and heartbroken. Rishi Sunak has called it an appalling attack. Anthony Albanese is demanding accountability from Israel. But what exactly does that mean? What should accountability look like? What should the independent investigation that’s been promised, actually involve? And could this moment lead to a serious change in the conduct of this war? David Speers explores this potential tipping point in the conflict with Reverend Tim Costello, one of Australia's best known leaders in international aid.
