The violence suggested perilous divisions in the ranks of Sudan’s security forces, which devolved into a fractious mix of regular and paramilitary forces under Mr. al-Bashir, and it appeared to give fresh momentum to the power-sharing talks that culminated in the news conference early Wednesday.
A military spokesman, Lt. Gen. Yasser al-Atta, said that alliance of protest groups would control two-thirds of the seats on a 300-seat transitional legislative council. Other opposition parties would hold the rest.
He said the two sides would spend the first six months of the transition period negotiating peace agreements with rebel groups from Darfur, Blue Nile and South Kordofan, who have been fighting the central government for years.
The three-year transition period is a compromise between the military’s demand for a two-year period and protesters who wanted four years.
But throughout the talks a key sticking point has been the composition of the sovereign council that would sit over a technocratic, civilian-dominated government. The generals who seized power from Mr. al-Bashir said they should be in charge, and have appeared to enjoy the backing of powerful regional players including Saudi Arabia, Egypt and the United Arab Emirates.
Distrustful protesters, who say they have learned the lesson of recent failed revolutions in countries like Egypt, insist they should hold power during the transition.
On Wednesday both sides indicated they were close to a finalized deal. “Viewpoints are close and, God willing, we will reach an agreement soon,” the protest leader Satea al-Hajj, who appeared alongside General al-Atta, told reporters.
