Sudan paramilitary chief admits withdrawal from capital

"All those who think that there are negotiations or agreements in process with this diabolical movement are mistaken," Daglo said, in reference to the army.

"We have neither agreement nor discussion with them -- only the language of arms."

Army chief Abdel Fattah al-Burhan on Saturday also vowed not to back down, after a decisive blitz in which the army reclaimed the presidential palace, the war-damaged airport and other key sites in the city centre where buildings are burned and bullet-scarred.

"We will neither forgive, nor compromise, nor negotiate," Burhan said, adding that victory would only be complete when "the last rebel has been eradicated from the last corner of Sudan".

Despite the military's reclaiming of Khartoum, Africa's third-largest country remains essentially divided in two by the war. The army holds sway in the east and north while the RSF controls most of the vast Darfur region in the west, where it is rooted, and parts of the south.

Pope Francis, recovering from a life-threatening bout of pneumonia, on Sunday issued written prayers and urged new negotiations as soon as possible in Sudan.

Appeal for new talks 

Early in the war the United States and Saudi Arabia conducted mediation but multiple ceasefires collapsed.

US Secretary of State Marco Rubio on Thursday said Washington hoped to do more diplomatically to end the war.

Rubio said he was "engaged" on Sudan and had discussed the war with international players including Kenyan President William Ruto and Ethiopian Prime Minister Abiy Ahmed.

Rubio's predecessor Antony Blinken tried extensively to broker an end to the war but ultimately voiced disappointment at the failure to do so.

The United States has imposed sanctions on both sides. It accused the army of attacks on civilians and said the RSF had "committed genocide" in Darfur.

Following a year and a half of defeats to the RSF, the army late last year began pushing through central Sudan to Khartoum.

Analysts have blamed the RSF's losses on strategic blunders, internal rifts and dwindling supplies.

On Thursday night, however, witnesses in the Blue Nile state capital Damazin reported that both its airport and the nearby Roseires Dam came under drone attack by the paramilitaries and their allies for the first time in the war.

The army later said it had shot down the RSF drones.

Almost 500 kilometres (310 miles) to the northwest in El-Obeid city, a medical source on Sunday told AFP that an RSF strike killed a child and wounded eight other people.

It is the latest such attack reported by medical sources since the military in February said it had broken an RSF siege of the North Kordofan state capital.

In a January report, a United Nations panel of experts tasked with monitoring an arms embargo on Darfur found "credible" accusations that the United Arab Emirates was funnelling "military support" to the RSF through neighbouring Chad.

Abu Dhabi has denied the allegations.
