South Sudan’s government has defended the military and other security organs, stressing they will never be dissolved.

The opposition groups have recently demanded that the security sector should be restructured and President Salva Kiir should not lead the transitional government.

Speaking to Radio Tamazuj on Tuesday, South Sudan’s presidential spokesman Ateny Wek Ateny said "The current government will never negotiate with the opposition on dissolution of the military and other security organs".

"The demands by the opposition to dissolve the security sector are impossible. How can you dissolve the army? It is actually an obstacle created to impede the peace process," Ateny said.

"SPLA will never be dissolved," he added.

Ateny pointed out that any proposal calling for President Kiir to step down is “totally unacceptable” and “should be declared dead on arrival.”

 He stressed that Kiir should lead the transitional period. “How can you say Kiir should not lead the transitional period? Without Salva Kiir, there will not be a government. Kiir is the one to bring about peace in the country right now,” he said.

Separately, the presidency has expressed its disappointment over the recent UN report accusing more than 40 South Sudanese military officials of committing war crimes and crimes against humanity.

The presidential spokesman, Ateny Wek Ateny, rubbished the report and asked the world body to reveal the names of those identified in the report.
