ADDIS ABABA  - Sudan and South Sudan inked a series of deals on security and cooperation on Thursday, hailed by their presidents as ending the rivals’ conflict but falling short of a comprehensive solution. South Sudan’s President Salva Kiir said the agreement “brings to an end the long conflict between our two countries,” while his counterpart Omar al-Bashir said he would “seize the historic opportunity and journey towards building peace.” The leaders signed a “cooperation agreement” after marathon talks in the Ethiopian capital that began Sunday, a day after the rivals missed a UN Security Council deadline to reach an agreement. However, the former civil war foes failed to strike a deal on the flashpoint region of Abyei.
