DEIR AL-BALAH, Gaza Strip (AP) — Palestinian health officials say Israeli warplanes struck a refugee camp in the central Gaza Strip, killing at least 40 people and wounding dozens. Sunday’s strike came as Israel vowed to press on with its offensive to crush the territory’s Hamas rulers, despite U.S. appeals for a pause in fighting to get aid to civilians. The soaring death toll in Gaza has sparked growing international anger, with tens of thousands from Washington to Berlin taking to the streets Saturday to demand an immediate cease-fire. The United States and Arab partners disagreed Saturday on the need for such a cease-fire. Israel said Hamas was “encountering the full force” of its troops.
