In recent days, Israeli tanks have rumbled into southern Gaza, starting with Khan Younis. It marks a grim new chapter in the war that the Gaza Health Ministry says has already killed over 17,000 Palestinians and the United Nations estimates has displaced 1.9 million people. Those who took refuge in southern Gaza from the military campaign that reduced the north to rubble over the past two months now find themselves stuck in a cramped, desperate patch of ever-shrinking land as Israel expands its invasion. The U.N. says pitched street battles and heavy bombardment have blocked aid groups from delivering supplies. That leaves desperate mobs to fight over food and water while patients and doctors struggle without critical medical equipment.
