At least 13 people have been killed - eight of them children - after a drone strike on a house in the Sudanese city of el-Obeid, says the Sudan Doctors' Network.
Most of the dead were part of the same family, the medical group added.
Although no group has claimed responsibility, the medics say the paramilitary Rapid Support Forces (RSF) carried out the attack in an area controlled by the army, which it has been trying to penetrate for months.
As the civil war between Sudan's army and RSF rebels approaches its third year, the scale of suffering has led the UN to label it the world's worst humanitarian crisis.
To date, more than 11 million people have been displaced due to the violence, with hundreds of thousands reported dead. Widespread sexual violence is also being employed as a weapon of war.
Both the RSF and the Sudanese Armed Forces face accusations of committing atrocities.
Witnesses described the drone attack as occurring in a residential neighborhood, with the Sudan Doctors' Network stating it reflects a growing trend of indiscriminate violence and systematic bombing of residential areas.
Although the city of el-Obeid remains under army control, analysts indicate that it is a significant target for the RSF, given its strategic position between Khartoum and the Darfur region, where they govern and face accusations of genocide.
This strike follows a previous RSF attack on a power plant in el-Obeid, as well as an attempted RSF drone attack on a large hydroelectric dam.
