The attack was directed at the city of Kabkabiya, where many people had gathered for the weekly market, according to a brief statement from the organization Emergency lawyers. Hundreds of people were also injured.
"This attack on civilians on a market day is a flagrant violation of international law. We demand an immediate investigation into this crime," the organization writes on social media, and attaches a picture that appears to show a mass grave.
The organization has documented war crimes and human rights abuses during the catastrophic civil war in Sudan.
At least 65 dead in Khartoum
The France-based news site Sudan Tribune reported on Monday about airstrikes on Kabkabiya, citing various witnesses and organizations. At the time, it was reported that dozens of people had been killed.
The city is controlled by the paramilitary militia Rapid Support Forces (RSF), which is fighting against Sudan's regular army. About 18 miles west, the capital of North Darfur state, al-Fashir, has been under siege by RSF forces for over six months.
In another attack, at least 65 people were killed in the city of Omdurman in Khartum state, after paramilitaries targeted a bus, according to the state governor Ahmed Othman Hamza, who has ties to the army.
He calls the attack a "massacre", and adds that hundreds were injured.
Many flee to South Sudan
The war has been going on for about 20 months. Both the Sudanese army and RSF are accused of widespread atrocities, where violence is directed against civilians and targets. Tens of thousands of people have been killed and millions have been driven into flight within Sudan. According to the UN, nearly 10,000 people flee the country every day to seek refuge in South Sudan. The number has increased sharply in recent weeks.
Most of those seeking shelter are women and children.
The fighting in Sudan broke out in April 2023 and is between arch-rivals General Abd al-Fattah al-Burhan and his former deputy, Mohamed Hamdan Daglo, who is the leader of the Rapid Support Forces, RSF.
RSF was formed in 2013 from the janjaweed militias, the armed groups that Sudan's former dictator Omar al-Bashir had sent out to spread terror and quell the uprising in conflict-ridden Darfur in western Sudan in the early 2000s.
Both parties have repeatedly been accused of war crimes.
