The Democratic Republic of Congo and defeated M23 rebels failed to sign a hoped-for peace deal Monday, after Kinshasa demanded the agreement be revised, a Ugandan government official said.
The "DRC delegation has aborted the signing of agreement with M23," Ugandan government spokesman Ofwono Opondo said, adding that the meeting was "adjourned sine die (without date)."
The UN hoped a peace deal would be a key step to ending decades of war in the Great Lakes region.
The rebels, one of many armed groups operating in the mineral-rich but impoverished east of the DR Congo, were routed by the national army, who are backed by a 3,000-strong special United Nations intervention brigade.
Allegedly supported by neighboring Rwanda and Uganda but seemingly abandoned by their sponsors due to international pressure, the M23 announced last week that their 18-month insurgency was over. They were expected to put this in writing in Uganda on Monday.
"Our hope is that we have a firm commitment from the M23 rebels to renounce their use of arms," said DR Congo government spokesman Lambert Mende said earlier.
The M23, a mainly ethnic-Tutsi force who mutinied from the Congolese army, did not confirmed Monday's meeting. But with no more military leverage they were seen as having little room for maneuver.
Rebel delegate Roger Lumbala said earlier the deal would be signed on Monday evening, with journalists summoned to Uganda's State House in Entebbe, a town close to Kampala on the shores of Lake Victoria, to await the ceremony.
The agreement was expected to settle the fate of about 1,500 M23 fighters who have crossed into Uganda and are languishing in camps along the border. Uganda has refused to hand them over to the DR Congo.
Around 100 more injured rebels have crossed to Rwanda.
Mende said the rebels would be dealt with "case by case" — with many rank-and-file fighters expected to be given the option to return to the army.
More complicated is the fate of around 100 M23 commanders. These include M23 leader Sultani Makenga, accused of participating in several massacres, mutilations, abductions and sexual violence, sometimes against children.
The United Nations' special envoy to the Great Lakes, Mary Robinson, told AFP the accord would be "a very important step for peace".
She said the deal will also be followed by operations to neutralize other rebel groups in a concerted effort to end one of Africa's most brutal and longest-running wars.
This would be "new and welcome news for the people... who have tolerated or have had to endure for far too long these armed groups, with the raping and re-raping, with the displacement of people," she said.
"It has been intolerable, and now there really is hope," said the former Irish president.
Role of Uganda and Rwanda
But even if a deal is signed, stabilizing eastern DR Congo will not be easy. Previous peace deals for the region have foundered because they were not implemented or did not address underlying problems.
Oxfam on Monday warned the "conflict is far from over", noting over 30 other armed groups operate in the region and civilians risk violence on a daily basis.
Human Rights Watch last week warned "numerous challenges remain," noting eastern DRC "has been beleaguered by abuses by other armed groups, as well as by the Congolese army."
Robinson said she believed Rwandan President Paul Kagame and Ugandan President Yoweri Museveni — who deny backing the M23 — were committed to an 11-nation regional peace agreement signed in February.
She said the priority would now shift to defeating the DR Congo-based Democratic Forces for the Liberation of Rwanda (FDLR), a descendant of Hutu extremist groups that carried out the 1994 genocide in Rwanda.
Rwanda's minority Tutsi-led government views the FDLR as a major security threat, and dealing with the group is seen as crucial to addressing the neighboring country's concerns and preventing the emergence of yet another Rwandan-backed proxy.
But not everyone in the DR Congo was convinced.
Several aid agencies and Congolese civil society groups last week dismissed the peace negotiations as "nonsense" and denounced the impending "integration of criminals and foreigners" back into the army.
A researcher for the Enough Project, a US group campaigning against war crimes, said Rwandan and Ugandan meddling could still scupper a deal.
"Museveni does not hide his feelings for the M23 when he demands a general amnesty and their unconditional reintegration," Fidel Bafilemba said.
"The fact that Uganda says it won't extradite the rebels leads one to think there could be a plan B to rebuild the rebels."
