The latest attack was due to the African Union's rejection of any "intervention" in the civil war, which killed more than 20,000 people.
The Sudan Armed Forces (SAF) said the paramilitary rapid support force (RSF) killed seven people in El-Fasher, the capital of the northern Darfur state of West Sudan.
A statement from the military-aligned government said Monday that the RSF shelling that began late Sunday targeted residential communities, killing seven people, including women and children, and at least 15 people were taken to hospitals.
The Army also said the city's RSF shelling killed nine people on Sunday.
Since May 2024, El-Fasher has fought fiercely between the SAF and the RSF, despite international warnings that the risk of violence in the city is the main humanitarian hub of the five Darfur states.
For more than a year, the RSF has tried to control it, located in Khartoum, 800 kilometers (500 miles) southwest of the capital, which carried out regular attacks on the city and created two major famine camps for its outer skin.
According to the United Nations, the RSF and SAF have been in a brutal power struggle since April 2023, killing thousands of people and pushing Sudan to one of the world's worst humanitarian crises.
According to data from the United Nations and local figures, more than 20,000 people were killed and 15 million were displaced in the third year of the brutal civil war. However, some U.S. researchers estimate that the actual death toll is as high as 130,000.
Meanwhile, the African Union (AU) said on Monday that it will not accept “any intervention” from Sudan after the RSF is accused of receiving weapons from the United Arab Emirates (UAE).
Last week, the Sudanese government cut off diplomatic relations with the UAE, accusing it of providing weapons to the RSF.
Amnesty International also accused the UAE of violating the UN arms embargo and providing weapons to the RSF.
The UAE rejected these claims as "founded without foundation."
AU President Mahamud Ali Youssouf said: "The committee's position is that the member states are sovereign states and the African Commission will not accept any intervention in the Sudan's internal affairs."
"We will not support any intervention, any intervention in the Sudan crisis," he said.
However, Youssouf declined to comment on the possible role of the UAE in the conflict. "Sultan is not accusing the UAE of role; Sudan is provided by the Sudan."
Djibouti's Foreign Minister was elected as head of the Pan-African organization in February, inheriting records of multiple conflicts and invalid declarations.
His first priority in the post was the Sudanese Civil War, which actually divided the country into two parts.
Both sides were charged with war crimes.
In recent days, the Army has increased drone attacks attributed to the RSF, marking a turning point in the two-year conflict.
The drone attacks also targeted strategic sites in Port Sudan, Port Sudan, temporary seats in the government and logistical humanitarian centre.
In February, UN Secretary-General Antonio Guterres urged to stop the "weapon stream" entering Sudan.
