Israel has failed to crack down on armed gangs attacking food convoys in Gaza, despite a pledge to do so in mid-October to help ward off famine in the Palestinian enclave, according to three U.N. and U.S. officials familiar with the matter. The commitment, made behind closed doors, seemed like a breakthrough because, since the beginning of the war in October 2023, the international community has struggled to enlist Israel's support to improve the dire humanitarian situation in the war-ravaged territory, the three senior officials said.
