Sudan's rival military factions agree to cease-fire as tensions remain high

Sudan's rival military factions have clashed over the future of the country. A cease-fire just announced by neighboring South Sudan brings some hope that the conflict may come to an end.

Over 330,000 people are internally displaced and more than 100,000 have fled Sudan since fighting broke out, causing a major humanitarian crisis. The U.N. refugee agency says that more than 800,000 people could flee Sudan and trigger a full-blown humanitarian catastrophe. The growing refugee crisis could plunge the already unstable and impoverished region into further chaos.

"The entire region could be affected," Egyptian President Abdel-Fattah al-Sisi told a Japanese newspaper on Tuesday as a Sudanese military envoy met Egyptian officials in Cairo.
