The U.N. independent investigator on the right to food accused Israel of carrying out a “starvation campaign” against Palestinians during the war in Gaza, an allegation that Israel vehemently denies.

In a report this week, investigator Michael Fakhri claimed it began two days after Hamas’ surprise attack in southern Israel that killed some 1,200 people, when Israel’s military offensive in response blocked all food, water, fuel and other supplies into Gaza.

Following intense international pressure — especially from close ally the United States — Netanyahu’s government gradually has opened several border crossings for tightly controlled deliveries. Fakhri said limited aid initially went mostly to southern and central Gaza, not to the north where Israel had ordered Palestinians to go.
