KHAN YUNIS, Palestinian Territories: More than 180,000 Palestinians have fled fierce fighting around the southern Gaza city of Khan Yunis in four days, the United Nations said Friday, after an Israeli operation to extract captives’ bodies from the area. Recent “intensified hostilities” in the Khan Yunis area, more than nine months into the Israel-Hamas war, have fueled “new waves of internal displacement across Gaza,” said the UN humanitarian agency, OCHA.
