The biggest of three Darfur rebel factions and the Sudanese Government accepted a peace agreement on Friday but two other rebel factions rejected the deal, casting doubt on whether it would end three years of bloodshed.
Both the government and a Sudan Liberation Army (SLA) faction said they agreed to the terms of the deal despite reservations in order to end the suffering in Sudan's arid west.
"I accept the document with some reservations concerning the power sharing," SLA faction leader Minni Arcua Minnawi told Nigerian President Olusegun Obasanjo, US Deputy Secretary of State Robert Zoellick and a host of senior diplomats meeting at Obasanjo's Abuja compound.
A spokesman for Minnawi's group said the main reservation was what they saw as insufficient representation in parliament.
The deal Minnawi's SLA faction agreed to was an amended version of an African Union (AU) drafted document produced after two years of talks. Western diplomats reworked parts that draft to win the support of rebels.
These amendments included stronger security guarantees for the rebels. In particular, provisions for rebel fighters to join the Sudanese armed forces were strengthened, as was a requirement Sudan disarm the Janjaweed militias it allegedly supports.
The government delegation, which had earlier accepted the AU draft, told a meeting of African heads of state and Western diplomats they would also accept the new terms.
"The priority for us is peace and the priority for us is to alleviate the humanitarian situation in Darfur," said Majzoub al-Khalifa, head of the government's negotiating team.
Sam Ibok, head of the AU mediation team, said the government's main misgiving was the integration of rebels into security forces. Khartoum negotiators said the number of rebels to be absorbed into government security forces was too high.
'Big day for Darfur'
Mediators clapped and embraced at the end of the session with the government delegation and everyone in the room had a wide smile on their faces despite the all-night marathon talks.
AU chief mediator Salim Ahmed Salim said he would have been happier if all rebel factions had signed but this was nevertheless "a big day for the people of Darfur."
"In realistic terms the agreement between the government and the SLA Minni is a major development. The two of them working together can make a major contribution to a return to peace and normalcy in Darfur," Salim said.
Ibok said: "We are hoping those who are outside the agreements now will not do anything to impede the implementation because if they do there will be a robust response from the AU and the UN Security Council."
A rival faction of the SLA and the smaller Justice and Equality Movement (JEM) earlier rejected the deal citing a wide range of objections.
AU negotiators said they would bring rival SLA faction leader Abdel Wahed Mohammed al-Nur back to the talks to ask him if he would reconsider.
Minnawi has more support among SLA fighters than Nur, observers say, and JEM is marginal in terms of forces on the ground.
