Khartoum - Sudan's military council and opposition groups said they had agreed on Monday to a power structure for the country's transition but have yet to decide how long it will last or the make-up of transitional bodies.
The apparent progress was offset by rising tension in the capital Khartoum, where paramilitary forces patrolled the streets into the evening, using tear gas and gunfire to disrupt protests blocking roads.
Protesters said counter-revolutionaries were inciting violence in an attempt to sabotage a political deal. An opposition doctors' group said three protesters had been wounded by gunfire, and several others by sticks or whips.
The military-civilian balance of power and the length of the transition have been key sticking points in talks between the council and an alliance of protest and opposition groups since former President Omar al-Bashir was ousted on April 11.
Those points will be addressed on Tuesday, according to Transitional Military Council (TMC) spokesman Lieutenant General Shams El Din Kabbashi and Taha Osman Ishaq, a spokesman for the Declaration of Freedom and Change Forces opposition alliance.
Protesters are pushing for a civilian-led transition and have kept up demonstrations against the council since military officers removed Bashir, who is now facing multiple criminal investigations.
For a second day on Monday demonstrators blocked Nile Street, a major avenue running south of the Blue Nile, placing burning branches and stones across the road, as well as several other streets north and south of the river.
In the morning, police and paramilitary Rapid Support Forces (RSF) dismantled barricades and dispersed about 100 protesters who had blocked a road leading from Khartoum North to al-Mek Nimir Bridge and the centre of the capital.
Later, RSF men fired gunshots to disperse protesters near Blue Nile bridge and thick clouds of tear gas were fired near Jumhuriya Street south of the river, where the RSF were seen beating a rickshaw driver as they patrolled in vehicles armed with sticks and guns, witnesses said.
Protesters demanding a swift handover of power to civilians have been camped at a sit-in outside the Defence Ministry compound in central Khartoum since April 6, as the military has negotiated with the opposition alliance over the transition.
Talks resumed on Monday, and both sides said they had produced agreement on the duties and authorities of sovereign, executive and legislative bodies.
"We discussed the structure of the transitional authority and agreed on it completely, and we also agreed on the system of governance in the transitional period," said Kabbashi.
"We will continue tomorrow with talks on the ratio of participation on the sovereign level ... and the length of the transitional period," he said. "God willing, we will agree on these two points."
The Sudanese Professionals' Association, which leads the opposition alliance, has accused the TMC of expanding its powers as talks over the transition have stalled, threatening a campaign of civil disobedience to up pressure on the military.
"The situation now on public roads, bridges and in neighbourhoods expresses the state of popular discontent with the procrastination and the consumption of time by the military council," the SPA said on Monday.
The TMC has said it is not seeking power and is open to further dialogue. General Mohamed Hamdan Dagalo, head of the RSF and deputy head of the TMC, told a military meeting on Monday that the armed forces and RSF were working to protect "security and stability" in Sudan.
Also on Monday, Sudan's public prosecution said it had charged Bashir and others with incitement and involvement in the killing of protesters.
Earlier this month, the public prosecutor ordered Bashir to be interrogated on charges of money laundering and financing terrorism. There has been no comment from Bashir, who is in prison in Khartoum.Reuters
