Sporadic gunfire rang out early Monday in the South Sudan capital, Juba, in what a senior military official said were clashes between factions of the country's military, AP reported. Col. Philip Aguer, the South Sudan military spokesman, said some military installations in Juba had come under attack from armed soldiers who have since been repulsed. Aguer offered no more details, saying an investigation was underway and that the situation was tense but not likely to deteriorate. "So far the army is in full control of Juba," he said.
