Releasing their imprisoned colleagues will be a top priority for South Sudanese rebels during peace talks that are to start Friday in Ethiopia. The government arrested some pro-rebel officials during the initial outbreak of fighting in South Sudan's capital, Juba, last month.
Delegates of former South Sudanese vice president Riek Machar see the release of detained prisoners as an important goal during the peace talks.
The rebels and delegates of the South Sudanese government are set to start face-to-face negotiations Friday.
Spokesperson for the rebel troops Hussein Mar Nyuot said the issue of the detainees is a very serious matter, as he feels they should also participate in the negotiations:
“With the prisoners, they were actually detained because of [the] alleged coup. And these are the senior members of the SPLM, which is actually the ruling party of the country. And we want them to be part of these talks because what caused the problem is actually an issue of conflict within the SPLM,” said Nyuot.
Delegates arrived in Addis Ababa on Wednesday and Thursday, and are separately meeting with officials of the East African bloc IGAD (Intergovernmental Authority on Development).
The negotiations will start while fighting continues in South Sudan. Rebels reclaimed the key city of Bor Wednesday, 120 kilometers outside Juba. They also control Jonglei state and the two oil-rich states of Upper Nile and Unity.
Along with a possible ceasefire, negotiators will likely discuss the outbreak of ethnic violence between supporters of Machar, a member of the Nuer tribe, and supporters President Salva Kiir, an ethnic Dinka.
But spokesperson Nyuot said the topics to be discussed have not been decided.
“We are positive, and will see how it goes tomorrow. I do not want to predict. I do not want to set the agenda before people actually agree on the agenda. I do not want to expose our agenda, what we are coming, because the mediators will have to put the agenda together,” said Nyuot.
Fighting in South Sudan started December 15, when a group of soldiers attacked army headquarters in Juba. The next day, President Kiir accused Machar of attempting a coup.
The fighting has killed more than 1,000 people and displaced about 200,000 others. It is feared the conflict might escalate into an all-out civil war.
President Kiir has said there will be no power-sharing deal.
South Sudan is the world's newest nation, having separated from Sudan in July 2011 after decades of war.

Machar told VOA South Sudan in Focus Wednesday that President Kiir was responsible for much of the unrest, and that peace cannot be achieved under Kiir's leadership.
"He has disunited the country. There is a massacre in Juba, 'ethnic cleansing' in Juba," he said. "I don't think Salva Kiir can unite the people anymore."
Machar said South Sudan's citizens should join him in a bid to force the president to step down, if he does not do so voluntarily.
