A key military leader in Sudan has promised to abide by a power-sharing agreement with the opposition.
Mohamed Hamdan "Hemeti" Dagolo - widely regarded as Sudan's most powerful man - made the pledge in a BBC interview as the two sides prepared to sign the landmark deal later on Saturday.
Its aim is to end months of unrest and pave the way for civilian rule.
Pro-democracy protests and violent repression gripped Sudan after long-time ruler Omar al-Bashir was ousted.
Under the new deal, a sovereign council, consisting of six civilians and five generals, will run the country until elections.
The two sides have agreed to rotate control of the council for just over three years. A prime minister nominated by civilians is due to be appointed next week.
"We will stick to every single letter we have agreed on," Hemeti told the BBC's Zenab Badawi.
"Even without the agreement we [would] have to work in this direction because it's in the country's interest," he added. "Therefore we have to carry out the agreement, stick to it and support it."
Hemeti is the commander of the Rapid Support Forces (RSF) - which grew out of the notorious Janjaweed militia that was accused of carrying out a genocide in the Darfur region of western Sudan.
The RSF have been blamed for recent abuses, including the June 3 massacre during which more than 120 people were reportedly killed, with many of the dead dumped in the River Nile.
RSF leaders have denied planning the killings, which they say were carried out by rogue elements.
Asked about the massacre in the BBC interview, Hemeti said there had been "systematic plotting and conspiracy" to tarnish the reputation of the RSF, whom he described as "protectors" and not killers.
The unrest in Sudan can be traced back to December 2018, when then President Bashir's government imposed emergency austerity measures.
Cuts to bread and fuel subsidies sparked demonstrations in the east over living standards and the anger spread to the capital.
The protests broadened into demands for the removal of Mr Bashir - who had been in charge for 30 years.
In April, the president was overthrown by the military after sit-ins outside the defence ministry, but demonstrators then wanted to ensure authority was swiftly transferred to a civilian administration.
A council of generals led by Lt-Gen Abdel Fattah Abdelrahman Burhan assumed power but it has struggled to return normality to the country.
The army is not a unified force in Sudan. Paramilitary organisations and various Islamist militias hold some sway.
