Speaking on CBS, White House National Security Council spokesman John Kirby said the US has been speaking to Israel 'about a transition to low-intensity operations' in Gaza. "We believe it's the right time for that transition. And we're talking to them about doing that," he said on 'Face the Nation'. The comments expose the growing differences between the close allies on the 100th day of the war. The unprecedented level of death and destruction in Gaza has led South Africa to lodge allegations of genocide against Israel at the International Court of Justice.
