U.N. peacekeepers said Tuesday that combat is ongoing in South Sudan despite the opening of peace talks meant to end fractional fighting. U.N. spokesman Farhan Haq said that U.N. peacekeepers reported Tuesday continuing fighting south of the city of Bor in oil-producing Jonglei state. He said that explosions were heard to the southeast. Peacekeepers are on 24-hour patrols in Juba, the capital, but the situation remains tense there. Talks in Ethiopia between representatives of South Sudan President Salva Kiir and former Vice President Riek Machar were to resume Tuesday.
