CAIRO: The United Nations’ food agency says it has temporarily paused aid distribution in Sudan’s famine-hit Zamzam displacement camp of a half-million people as fighting intensifies between the country’s warring sides, and it warns that thousands could now starve. The World Food Program said Wednesday that fighting in the past two weeks between the military and a paramilitary group in Sudan’s civil war has forced its partners to leave the camp in western Darfur for safety.
