The United Nations warned Sunday that Sudan is "on the verge of an all-out civil war" that could destabilize the entire region, following an air strike in Omdurman, a suburb west of Greater Khartoum, which left at least 22 dead and dozens wounded.

UN Secretary-General Antonio Guterres announced that "the ongoing war between the armed forces has pushed Sudan to the brink of an all-out civil war that could destabilize the entire region," his deputy spokesman Farhan Haq said in a statement.

Guterres condemned the air strike in Omdurman, Sudan, which reportedly killed at least 22 people.

The Ministry of Health in Khartoum State said in a statement on Saturday that "a bombardment by warplanes at dawn on Saturday killed 22 citizens and left a large number of wounded" in the Dar al-Salaam al-Amriyah area in Omdurman.

The ministry posted on Facebook video clips of dead bodies on the ground, some of them with limbs cut off.

The Rapid Support Forces accused the army of carrying out the raid, noting that it killed at least 31 people.

In a statement, it condemned "the barbaric attack carried out by the coup forces on the citizens of Square 22 Dar al-Salam," describing it as a "heinous crime against humanity."

It said that it led to "the killing of more than 31 people and the wounding of dozens of civilians."

Residents of Dar al-Salam al-Amriyah confirmed to AFP on Sunday that what they witnessed was "an air strike that killed 22 people, including children," noting that the army is the only one of the two parties to the conflict that has an air force.

However, the armed forces denied in a statement on Sunday, "The Air Force dealt yesterday with any hostile targets in Omdurman."

The army accused the Rapid Support Forces of "bombing residential areas with artillery and missiles, coinciding with our planes flying to try to accuse the armed forces of targeting citizens falsely and falsely."

Witnesses reported more air strikes Sunday near the presidential palace.

According to witnesses, "violent clashes with heavy weapons" also took place in the southern neighborhoods of Khartoum.

Meanwhile, witnesses reported that civilians began digging graves to bury those killed in Saturday's airstrike.

Since the war began, many corpses have been left to rot in the streets in Khartoum and Darfur.

Since April 15, Sudan has been witnessing battles between the army led by Abdel Fattah al-Burhan and the Rapid Support Forces led by Muhammad Hamdan Dagalo, known as "Hemedti".

The conflict has led to more than 2,800 deaths and the displacement of more than 2.8 million people, of whom more than 600,000 have sought refuge in neighboring countries, according to data from the International Organization for Migration, especially to Egypt in the north and Chad in the west.

The battles are concentrated in the capital, Khartoum, and areas close to it, in addition to the Darfur region, where the United Nations has warned that what it is witnessing may amount to "crimes against humanity" and the conflict in it is taking on more and more ethnic dimensions.

According to the spokesman's statement, Guterres expressed his "concern about reports of renewed fighting in the states of North Kordofan, South Kordofan and Blue Nile," denouncing "a complete disregard for humanitarian law and human rights law."

He renewed his call for a cessation of hostilities and a "commitment to a permanent cessation of hostilities."

The city of El-Obeid, the capital of North Kordofan state, witnessed clashes on Saturday night and Sunday afternoon between al-Burhan's forces and Dagalo's forces, according to eyewitnesses.

On Friday, residents of the city of Bara, 50 km northeast of El-Obeid, told AFP that "(the) Rapid Support Forces are attacking the city of Bara and attacking banks and government facilities."

Amidst these developments, the civil aviation authorities announced "the extension of the closure of Sudanese airspace to all air traffic until the thirty-first of July, with the exception of humanitarian aid flights and evacuation flights after obtaining a permit from the competent authorities," according to a statement posted on the airport's page. Khartoum International on Facebook Sunday night Monday.
The two parties to the conflict concluded several truces, often with the mediation of the United States and Saudi Arabia, which witnessed many violations.

Both the African Union and the IGAD Organization for Development in East Africa are trying to mediate a solution to the crisis in Sudan.

In the context, the spokesman for the Executive Secretary of the organization, Nour Mahmoud Sheikh Al-Jumaa, said, "It is scheduled to hold an IGAD session for the heads of state and government of the Quartet (mechanism) concerned with Sudan in Addis Ababa on Monday."

Khaled Omar Youssef, a former civil minister who was removed from his position after the military coup carried out by Al-Burhan in 2021, wrote in a tweet that he had arrived "accompanied by a number of Sudanese civil actors to Addis Ababa, which is witnessing important activities aimed at stopping the war in Sudan."

He continued, "We are working during this visit to communicate with Sudanese, regional and international actors in order to accelerate efforts to bring peace to our country. This damned war must stop."

In turn, Egypt, which is close to Al-Burhan, announced that it will host a summit of the countries neighboring Sudan on Thursday, "to discuss ways to end the current conflict and the negative repercussions on neighboring countries," according to a statement by the Egyptian Presidency.

Even before the war broke out, Sudan was one of the poorest countries in the world, with 25 million people, representing more than half of the population, in need of humanitarian assistance and protection, according to the United Nations.
