In the capital, Khartoum, the intensity of fighting eased on the second day of a three-day truce.
Taking advantage of relative calm, many residents in Khartoum and the neighbouring city of Omdurman emerged from their homes to seek food and water, lining up at bakeries or grocery stores after days of being trapped inside by the fighting between the army and a rival paramilitary group.
Some inspected shops or homes that had been destroyed or looted.
"There is a sense of calm in my area and neighbourhoods," Mahasen Ali, a tea vendor who lives in Khartoum's southern neighbourhood of May, said.
"But all are afraid of what's next."
Still, gunfire and explosions could be heard in the city although residents said clashes were in more limited pockets, mainly around the military's headquarters and the Republican Palace in central Khartoum and around bases in Omdurman across the Nile River.
With the future of any truce uncertain, many took the opportunity to join the tens of thousands who have streamed out of the capital in recent days, trying to get out of the crossfire between the forces of Sudan's two top generals.
The generals' war for power since April 15 has pushed the population to a near breaking point.
Food has grown more difficult to obtain, electricity is cut off across much of the capital and other cities and many hospitals have shut down.
Multiple aid agencies have had to suspend operations, a heavy blow in a country where a third of the population of 46 million relies on humanitarian assistance.
Many Sudanese fear the army and its rival Rapid Support Forces will escalate their battle once removal of foreigners that began on Sunday is completed.
Large numbers of people have been making the exhausting 15-hour drive across the desert to access points out of the country - to the city of Port Sudan on the eastern Red Sea coast and to the Arqin crossing into Egypt at the northern border.
Large crowds of Sudanese and foreigners waited in Port Sudan, trying to register for a ferry to Saudi Arabia.
Dallia Abdelmoniem, a Sudanese political commentator, said she and her family arrived on Monday and have been trying every day to get a spot.
"Priority was given to foreign nationals," she told the Associated Press.
Saudi Arabia said on Wednesday it had helped 1674 people from 56 countries, as well as 13 of its own citizens, leave Sudan.
Tens of thousands of Khartoum residents have also fled to neighbouring provinces or even into already existing displacement and refugee camps within Sudan that house victims of past conflicts.
