Plans to force Palestinians into a “humanitarian city” in Gaza would be akin to a concentration camp, a former Israeli prime minister has said. Ehud Olmert claimed construction of the camp would mark an escalation in the conflict and that he now considers Israel to be committing war crimes in Gaza and the West Bank.

At least 31 Palestinians were fatally shot on their way to an aid distribution site in the Gaza Strip on Saturday, while Israeli airstrikes killed at least 28 Palestinians including four children, Palestinian hospital officials and witnesses said.

Israel and Hamas appeared no closer to a breakthrough in talks meant to pause the 21-month war and free some Israeli hostages.
