UNMISS Chief: South Sudan Peace Process Limping Along Dimo Silva Aurelio JUBA , SOUTH SUDAN - A top U.N. official says South Sudan's peace process is limping along and faces serious challenges that could lead to a further escalation in violence. David Shearer, the special representative of the U.N. Secretary General in South Sudan (UNMISS) told reporters in Juba Tuesday urgent action is needed to put the peace process back on track. "The cabinet is meeting irregularly, and people tell me that they want to see the president and vice presidents meeting and working closely together more often. The transitional National Legislative Assembly is yet to be reconstituted, so necessary new laws are not being passed and progress on the constitution has been delayed. Critically, there has been almost no movement on the areas of security sector reform," said Shearer. The UNMISS boss, who recently returned to Juba from New York, where he briefed the U.N. Security Council on the situation in South Sudan, said military forces that were supposed to be trained, unified, and deployed are losing hope and have started deserting the country's training centers. "As a result of lack of food and of logistics and other things being supplied to these training centers, people started to leave, moving back. This is worrying because people are being disillusioned which leads to frustration and anger, and possibly which could mean more violence," Shearer told reporters. .
