Port Sudan, el-Fasher, West Kordofan and West Darfur have all seen heavy fighting.
Multiple attacks by Sudan’s armed forces (SAF) and the paramilitary Rapid Support Forces (RSF) have struck various locations across the country now in its third year of a civil war.
At least nine civilians, including four children, were killed and seven injured in attacks on Sunday by the RSF in el-Fasher, the capital of North Darfur state in western Sudan, according to the Sudanese army.
During a sweep of the city, the SAF killed six RSF members and destroyed three combat vehicles, according to the statement. There was no immediate comment from the RSF on the army report.
El-Fasher is the last major city held by SAF in Darfur. For over a year, the RSF has sought to wrest control it, located more than 800km (500 miles) southwest of the capital, Khartoum, from the SAF, launching regular attacks on the city and two major famine-hit camps for displaced people on its outskirts.
In the meantime, Sudan’s civil defence forces announced on Sunday that they have full control over fires that erupted at the main fuel depot and other strategic sites in Port Sudan, the seat of the army-backed government, which has come under daily drone attacks blamed on the RSF over the past week.
The fires caused by a drone strike on the fuel depot on Monday had spread across “warehouses filled with fuel”, the Sudanese army-aligned authorities said, warning of a “potential disaster in the area”.
The Red Sea port city had been seen as a safe haven from the devastating two-year conflict between the SAF and RSF before the drone strikes began on May 4.
The attacks have damaged several key facilities, including the country’s sole international civilian airport, its largest working fuel depot and the city’s main power station.
On Tuesday, Sudanese authorities accused the RSF of being behind the drone strikes. The RSF has not commented on the allegations.
Port Sudan is the main entry point for humanitarian aid into Sudan. United Nations Secretary-General Antonio Guterres warned that the attacks “threaten to increase humanitarian needs and further complicate aid operations in the country”, his spokesman said.
Sudan’s army launched air strikes on the RSF in el-Khuwei in West Kordofan state and the state of West Darfur late on Saturday. El-Khuwei was captured by the RSF last week.
Activists and Sudanese accounts shared a video clip on social media showing the Sudanese army and their allied forces announcing that they had regained control over el-Khuwei after battles with the RSF on Sunday, according to Al Jazeera’s Sanad fact-checking agency.
Witnesses also reported drone strikes on Sunday, targeting the airport in Atbara, a city in the northern state of River Nile.
The RSF has been battling the SAF for control of Sudan since April 2023. The civil war has killed more than 20,000 people, uprooted 15 million and created what the UN considers the world’s worst humanitarian crisis.
