Air strikes and shelling have rocked Khartoum as Sudan enters a third week of fighting between rival military forces despite a ceasefire, and Australian officials continue to assist citizens and their families caught up in the conflict.
The latest round of strikes has prompted more civilians to flee and renewed warnings of wider instability if the war is not stopped.
A Department of Foreign Affairs and Trade (DFAT) spokesperson told the ABC they were in contact with 133 Australians and their families in Sudan.
"DFAT's immediate priority is their safety," they said.
"At least 138 Australians and their family members have now departed Sudan."
As dark smoke rose over Khartoum, a United Nations envoy offered a possible flicker of hope, saying the warring sides, who have so far shown no sign of compromise, were now more open to negotiations — though no date had been set.
More than 500 people have been killed and thousands wounded since April 15, when a long-simmering power struggle between the Sudanese army and the paramilitary Rapid Support Forces (RSF) erupted into conflict.
Meanwhile, Britain has evacuated 1,888 people on 21 flights from Sudan since the evacuation operation started on Tuesday, Britain's foreign ministry said.
On Friday, Britain said that it would cease evacuations of nationals and other eligible people after one final flight from Wadi Saeedna airfield on Saturday, as demand for spaces on its aircraft declined.
Ceasefires fail
Despite shelling early in the morning, residents of Khartoum and its neighbouring cities said the fighting had been less intense on Saturday (local time) than in recent days.
The fighting has pitched Sudan towards a civil war that has derailed an internationally backed transition toward democratic elections and could destabilise a volatile region.
The sides have continued to battle it out during a series of ceasefires mediated by foreign powers, notably the United States. The latest 72-hour truce expires at midnight on Sunday.
On Saturday, the RSF accused the army of violating the ceasefire in areas under its control.
There was no immediate comment from the army, which has previously blamed the RSF for violations and which said on Saturday its forces were continuing to work to end "the rebellion".
The prospects of negotiations between the leaders of the two sides have so far seemed bleak.
On Friday, army leader General Abdel Fattah al-Burhan said he would never sit down with the RSF's "rebel" leader, referring to General Mohamed Hamdan Dagalo, who is more commonly known as Hemedti.
The RSF chief in turn said he would talk only after the army ceased hostilities.
Nonetheless, the UN's special representative in Sudan, Volker Perthes, told Reuters he had recently sensed a change in the two sides' attitudes and they were more open to negotiations.
"The word 'negotiations' or 'talks' was not there in their discourse in the first week or so," Mr Perthes said.
Not a 'small rebellion'
Mr Perthes said the sides had nominated representatives for talks which had been suggested should take place in Jeddah, Saudi Arabia, or Juba in South Sudan.
However, he said there was a practical question over whether the parties could get there to "actually sit together".
The immediate task, Mr Perthes said, was to develop a monitoring mechanism for ceasefires.
Mr Perthes noted that he had told the Security Council both sides thought they could win the conflict, but he also said attitudes were changing.
"They have both accepted that this war cannot continue," he said.
At least 528 people have been killed and 4,599 wounded, the Sudanese health ministry told Al Jazeera.
The UN has said more than 75,000 people have been internally displaced by the fighting.
Former Sudanese prime minister Abdalla Hamdok, speaking at a conference in Nairobi, said the war must stop, warning of its ramifications not just in Sudan but in the region.
"This is a huge country, very diverse … I think it will be a nightmare for the world," he said.
"This is not a war between an army and small rebellion. It is almost like two armies – well trained and well armed."
Governments work on major evacuations
Tens of thousands of people have fled to neighbouring countries, while foreign governments have organised a major evacuation of expatriates.
Saudi state broadcaster Alekhbaiya said that a passenger ship with 1,982 people on board from 17 countries will arrive at Jeddah port on Saturday, and almost 5,000 people had already arrived.
Hundreds of Americans arrived at Port Sudan in the first US-run evacuation, completing a dangerous land journey under escort of armed drones.
American unmanned aircraft, which have been keeping an eye on overland evacuation routes for days, provided armed overwatch for a bus convoy carrying 200 to 300 Americans more than 800 kilometres to Port Sudan.
The US, which had none of its officials on the ground for the evacuation, has been criticised by families of trapped Americans in Sudan for initially ruling out any US-run evacuation for those among an estimated 16,000 Americans in Sudan who wish to leave.
US consular officials will be waiting for the Americans once they reach the dock in Jeddah.
US special operations troops briefly flew to the capital, Khartoum, on April 22, to airlift out American staffers at the embassy and other American government personnel.
More than a dozen other nations have already been carrying out evacuations for their citizens, using a mix of military planes, navy vessels and on the ground personnel.
Much of the fighting has played out in the capital Khartoum, where RSF fighters are embedded in residential areas and many residents are pinned down by urban warfare with scant water, food, fuel and power.
The fighting has also reawakened a two-decade-old conflict in the western Darfur region, where scores have died this week.
Pregnant 23-year-old Zamzam Adam said she was alone and stranded in labour as armed militias attacked and pillaged her village near the town of El Geneina in western Darfur and neighbours fled across the border into Chad.
"In our village, armed people came and burned and looted houses and we were forced to flee," said Ms Adam.
In Darfur, at least 96 people had died since Monday in inter-communal violence rekindled by the army-RSF conflict, said UN human rights office spokesperson Ravina Shamdasani.
