Gunfire shatters uneasy calm in South Sudan capital

NAIROBI, Kenya (AP) - A burst of heavy gunfire has been heard in South Sudan's capital, Juba, shattering a precarious calm that had settled here after more than 100 people died in fighting Friday night.

An Associated Press journalist heard the gunfire Sunday morning near the Jebel Kujur area, near a military base where first vice president and former rebel leader Riek Machar resides.

South Sudan is trying to emerge from a two-year civil war caused by political rivalry between Machar and President Salva Kiir.

The two leaders issued a joint call for calm after Friday's fighting which began outside the presidential compound where Kiir and Machar were meeting and soon spread through the city.

A similar skirmish in December 2013 sparked off the civil war that killed tens of thousands of people.
