The United Nations’ food agency says it has 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

The U.N. World Food Program said Wednesday that it was forced to suspend operations in and around the famine-hit Zamzam displacement camp in Sudan’s North Darfur because of escalating violence. “Intense fighting in Zamzam camp in Sudan’s North Darfur region has forced” the Rome-based agency “to temporarily pause the distribution of life-saving food and nutrition assistance in the famine-hit camp for displaced people.

An international aid worker says all roads around Sudan’s famine-stricken Zamzam camp in North Darfur are blocked and the security situation there has become “unbearable.”
