Shootings Underscore Fragile Transition in Sudan Jason Patinkin Gunfire as heard again in the Sudanese capital Khartoum Tuesday, as a dispute between different factions of the country's armed forces laid bare the fragility of the country's transition from military rule. Transitional government spokesperson Faisal Mohamed Salih blamed the unrest on the National Intelligence and Security Service (NISS), a shadowy armed group that was loyal to former President Omar al-Bashir, who was overthrown in a coup last April following months of street protests. NISS has been sidelined since the former president's overthrow, as Sudan's regular army and a paramilitary group called the Rapid Support Forces have become the country's most powerful armed groups. Both the army and the RSF are commanded by members of the ruling transitional government. Salih said shooting took place in Kafuri neighborhood in Khartoum North, Soba area near the U.S. Embassy, and in Riyadh east of the airport. Another small protest by NISS members took place in El Obeid town in the country's Kordofan region, Salih said. Reports said that the unrest began when soldiers being dismissed from NISS' Operations Division fired their weapons in the air in a dispute over payment of their severance. Many NISS soldiers have chosen to be dismissed with a severance as the country's armed forces restructure in the transition from military rule following Bashir's ouster. Government officials say negotiations began to quell the unrest. .
