An attack on an open market in the Sudanese city of Omdurman by a paramilitary group fighting the country's military killed 54 people and wounded many more, health authorities said Saturday.

The attack by the Rapid Support Forces on the Sabrein Market also wounded at least 158 others, the Health Ministry said in a statement. It was the latest in a series of deadly attacks in the escalated civil war that has wrecked the northeastern African country.

There was no immediate comment from the RSF.

Khalid al-Aleisir, minister of culture and government spokesperson, condemned the attack, saying that the casualties included many women and children. He also said the attack caused “widespread destruction to private and public properties.”

“This criminal act adds to the bloody record of this militia,” he said in a statement. “It constitutes a blatant violation of international humanitarian law.”

Sudan’s Doctors Syndicate condemned the RSF’s attack. It said one shell hit meters from al-Naw hospital, which received most of the market casualties.

It said most of the bodies taken to the hospital were of women and children, adding that the hospital has a significant shortage of medical teams, especially surgeons and nurses.

The conflict in Sudan started in April 2023 when simmering tensions between the leaders of the military and the RSF exploded into open fighting in the capital, Khartoum, and other cities across the sprawling northeastern African country.

Saturday's attack was the latest tragedy in the country’s brutal civil war. Last week, about 70 people were killed in a RSF attack on the only functional hospital in the besieged city of El Fasher in the western region of Darfur.

The conflict has killed more than 28,000 people, has forced millions to flee their homes and has left some families eating grass in a desperate attempt to survive as famine sweeps parts of the country.

It has been marked by gross atrocities, including ethnically motivated killing and rape, according to the United Nations and rights groups.

The International Criminal Court said it was investigating alleged war crimes and crimes against humanity. And the Biden administration had accused the RSF and its proxies of committing genocide in the war.

In recent months the RSF has suffered multiple battlefield blows, giving the military the upper hand in the war. It has lost control of many areas in Khartoum, the capital’s sister city of Omdurman, and the eastern and central provinces.

The military also regained control of the city of Wad Medani, the capital of Gezira province, and the country's largest oil refinery.
