Fighter of the opposition of the rapid support forces attacked a free market in the Sudanese city of Omdurman, killing 54 people.
The Sabrein market attack also injured at least 158 others, the Sudan Ministry said.
There was no immediate comment from the RSF.
The Minister of Culture and Government spokesperson Khalid Al-Aaleisir, condemned the attack and said that the victims understood many women and children. He also said that the attack had caused a “general destruction to private and public property”.
“This criminal act adds to the bloody file of this militia,” he said. “This constitutes a blatant violation of international humanitarian law.”
The conflict in Sudan began in April 2023 when simmering tensions between army leaders and the RSF exploded in open fights in the capital, Khartoum. The conflict has since spread across the country.
More than 28,000 people have been killed and millions of people forced to flee their homes. Famine has been declared in some parts of the country, where some families have used to eat grass to survive.
The conflict was marked by atrocities, in particular the murder and rape motivated ethnically, according to the UN and the human rights groups. The International Criminal Court said it was investigating alleged war crimes and crimes against humanity.
