Witnesses in several areas of Khartoum said there was a rare lull in fighting on Friday evening after a seventh straight day of explosions rocked the city.
Eid is meant to be spent “with sweets and pastries, happy children and people greeting relatives,” resident Sami al-Nour told AFP. Instead, there is “the stench of gunshots and blood all around us”.
Soldiers and paramilitaries fought fierce street battles in densely populated districts of Khartoum, with witnesses reporting explosions near the army headquarters in the city of half a million people.
On Friday evening, the army accused the RSF of violating the ceasefire, which included “indiscriminate bombing” of the airport and the presidential palace.
The previous two ceasefires earlier this week were also unsuccessful.
Plans are being made to evacuate foreign nationals, the United States, South Korea and Japan have deployed troops to nearby countries, and the European Union is taking similar steps.
On Friday, the US State Department said the fighting had made it too risky for Sudan to evacuate embassy personnel from Khartoum.
The Pentagon has mobilized in the East Africa region to evacuate US staff from Sudan’s capital.
Later, the RSF said it was ready to “partially” open “all airports” in Sudan for neighboring countries to evacuate their citizens.
It could not be independently verified which airports were under RSF control.
