South Sudan Government, Rebels Sign Ceasefire

Have been warring for more than a month

South Sudan's government and rebels fighting against it have signed a cessation of hostilities agreement that should at the least put a pause to five weeks of warfare.

Negotiators for the two sides have been meeting in Addis Ababa, Ethiopia, for weeks. Thursday's signing was the first real progress made.

The agreement should put an end to violence that has claimed thousands of lives and uprooted a half million people since fighting began Dec. 15 between the government and supporters of former Vice President Riek Machar.
