Riek Machar South Sudan rebel leader and former vice president has made a U-turn and agreed to sign a peace deal.
On Tuesday Riek Machar had refused to sign the peace deal.
Meanwhile, other opposition groups have signed several agreements, including a permanent ceasefire and a power-sharing deal that sees Machar returning as first vice president in the government.
“After intense negotiations by Sudanese mediators, Riek Machar agreed to sign the document on Thursday, August 30,” Sudanese Foreign Minister Al-Dierdiry Ahmed told reporters.
Machar and other rebel groups had earlier refused to sign the draft, saying their reservations had not been acknowledged in the text.
The rebel groups had differences over the functioning of a proposed transitional government, how many states the country should be divided into and on the writing of a new constitution.
