Congo's main rebel leader asked a UN envoy Saturday to arrange a face-to-face meeting with government officials during a second round of talks aimed at bringing peace to eastern Congo. The envoy, former Nigerian President Olusegun Obasanjo, and rebel leader Laurent Nkunda met for more than an hour in the rebel-held town of Jomba near the Ugandan border. "We have moved to advance the cause of peace," Obasanjo said. Nkunda said the former president told him the government "accepted the principle" of a face-to-face meeting but did not agree on where to hold the talks. Obasanjo met with President Joseph Kabila earlier this week.
