WINDHOEK, Namibia (CNN) -- Heads of state on opposing sides in the Congo war tried Sunday to resuscitate peace talks, but prospects appeared dim for a quick end to fighting involving troops from at least seven African nations.

Sunday's meeting in Namibia took place after Saturday talks in Zambia broke up in acrimony. Officials said the meeting would probably continue through Monday, but they announced no immediate progress.

Ugandan President Yoweri Museveni, who is backing the Congolese rebels, and Zimbabwean President Robert Mugabe, whose forces are backing Congo President Laurent Kabila, were part of the talks that began Sunday afternoon at a Windhoek hotel.

Asked for his view on the chances for success in the talks, Museveni said: "You don't eat before supper is cooked. Wait until after the meeting."

No neutral parties

Mugabe said one obstacle to a cease-fire was deciding which countries would oversee the peace process for the country, which is formally known as the Democratic Republic of the Congo.

Indeed, in a war that has troops from Zimbabwe, Angola, Namibia and Chad fighting alongside Kabila's forces against rebels backed by Rwanda and Uganda, finding neutral parties is no easy matter.

Mugabe told reporters he hoped the meeting would make progress toward a cease-fire in the five-month-old conflict, which has threatened the region's stability.

Simmering tensions

During the talks in Zambia, Angola called into question Zambian President Frederick Chiluba's credentials to mediate the talks, accusing Zambia of supporting Angolan UNITA rebels. Zambia denies the charge.

The Zambia talks apparently succeeded only in widening divisions, which diplomats said was evidence of the simmering tension in the region.

"Africa is at a crossroads. I doubt the region has the capacity nor the will to resolve the Congo war," said exiled Congolese politician Mutombo Kabunji.

"We may now see an escalation of the war, a stepped-up campaign by both sides," Kabunji added.

Sources close to the talks in Windhoek, which are hosted by Namibian President Sam Nujoma, said a rebel delegation was also expected to arrive, but it was uncertain whether they would participate directly. It was not clear if Kabila, who has refused to meet with the rebels, would attend.

Rwandan Vice President Paul Kagame, the real power in his country, was delayed in arriving because of mechanical trouble with his aircraft, said the sources, who spoke on condition of anonymity. Museveni dispatched his own plane to fetch Kagame, they said.

Angola's officials were also expected to attend.
