A U.N. agency warns that Israel’s military order to evacuate parts of Deir al-Balah in Gaza has displaced humanitarian workers and hindered essential services. The evacuation, indicating a potential ground operation, has reduced the humanitarian zone and escalated concerns about hunger and disease in crowded camps. Deir al-Balah’s mayor reports that 1 million people are trapped, surrounded by Israeli forces, with limited access to water and waste disposal. Fourteen of the city’s 19 water wells and two main water tanks are now out of service.
