Heavy gunfire erupted in South Sudan's capital of Juba on the evening of Nov. 21 near the residence of the country's former spy chief, Gen. Akol Koor Kuc, Reuters reported Nov. 22. While U.N. sources said the shootout followed an attempt by security forces to arrest Koor, an army spokesperson said that the clashes were linked to a misunderstanding between two units in charge of protecting the former head of the National Security Service.
