Sudan's government and southern-based rebels have agreed to extend a cease-fire by three months as part of ongoing talks to end a 21-year civil war.
A Kenyan negotiator, Lazaro Sumbeiywo, says the two sides agreed on Monday to extend the truce, which was first signed during talks in Kenya in 2002.
But he says Sudan's government and the rebel Sudan People's Liberation Army have yet to set a date to resume talks on sharing power and wealth in the south.
He told VOA that Sudanese officials have asked for time to resolve an 18-month conflict in the western Darfur region.
Khartoum has said it remains committed to finishing talks with southern-based rebels.
The talks in Kenya do not address Sudan's separate conflict with rebels in Darfur.
