JUBA, South Sudan (AP) — South Sudan President Salva Kiir met again with rival Riek Machar on Monday in neighboring Sudan amid fragile efforts to end their country’s five-year civil war, while the new U.S. ambassador to Juba told The Associated Press the U.S. is skeptical of the latest talks. The meeting mediated by Sudan’s President Omar al-Bashir in Khartoum resulted in “some points that enable South Sudan’s people to enjoy peace,” Sudan’s state-run news agency SUNA quoted Uganda’s President Yoweri Museveni as saying. It did not give details.
