Fresh gunfire rang out in South Sudan's capital early Tuesday, a day after the president announced he had defeated a coup attempt in the world's youngest nation, an AFP reporter said. The gunfire -- including the sporadic firing of heavy weapons -- resumed in the early hours of Tuesday and was still audible at 9:00 am (0600 GMT). It appeared to come from a military headquarters, a few kilometres (miles) from the centre of town. The streets of the capital were deserted, with only military vehicles to be seen and civilians barricaded in their homes.
