A drone attack on the town of Kalogi, in Sudan's South Kordofan region, is said to have hit a kindergarten, killing at least 50 people, including 33 children.
The Rapid Support Forces (RSF), the paramilitary group battling the army in Sudan's civil war, were accused of Thursday's attack by a medical organization, the Sudan Doctors' Network, and the army.
There was no immediate comment from the RSF.
The RSF in turn accused the army of hitting a market on Friday in a drone attack in the Darfur region, on a fuel depot at the Adre border crossing with Chad.
Sudan has been ravaged by war since April 2023 when a power struggle broke out between the RSF and the army, who were formerly allies.
The reports could not be independently verified.
According to the army-aligned foreign ministry, the kindergarten was struck twice with missiles from drones.
Civilians and medics who rushed to the school were also attacked, it added.
In response to the attack, a representative from UNICEF, Sheldon Yett, stated, Killing children in their school is a horrific violation of children's rights. He emphasized that children should never pay the price of conflict and urged all parties to stop these attacks immediately and allow safe access for humanitarian assistance.
The RSF accused the army of attacking the Adre crossing due to its role in facilitating the delivery of aid and commercial supplies.
The Sudan War Monitor, a research group, reported casualties among civilians and significant damage to a market from the attack.
Wedged between Sudan's capital Khartoum and Darfur, the region encompassing North Kordofan, South Kordofan, and West Kordofan has been a frontline in the civil war, with battles intensifying as the army pushes towards Darfur.
