About 26 Palestinians, mostly children, were killed in an Israeli bombardment of Khan Yunis city in south Gaza early on Saturday, the Palestinian news agency WAFA said. This comes as a first consignment of fuel has entered Gaza after Israel bowed to U.S. pressure for limited deliveries to allow wastewater treatment and the resumption of communications after a two-day blackout. The first delivery arrived from Egypt late Friday as U.N. officials warned of an increasingly desperate situation for 2.4 million Palestinians, and pleaded for a ceasefire.
