Sunday's attack, blamed on the RSF, which has been at war with the army since April 2023, also wounded 36 civilians, half of them children, the doctor told AFP on condition of anonymity for security reasons.

The bombardment struck residential areas in northern Omdurman, hitting civilians inside their homes and children playing on a football field, said the Khartoum regional government's media office.

The war between the RSF and the army has escalated in the capital this year, after the army's forces reclaimed swathes of territory lost to the RSF early in the conflict.

The army says units are now positioned less than a kilometre (about half a mile) from the presidential palace, which the RSF seized at the outset of the war.

The conflict has killed tens of thousands, uprooted more than 12 million and created the world's largest hunger and displacement crises.

From Khartoum alone, at least 3.5 million people have been forced from their homes due to the violence.

The war has nearly torn Sudan into two, with the RSF in control of much of the vast western region of Darfur and parts of the south, while the the army maintains a stronghold in the north and east.

The army has made gains in central Sudan and Khartoum in recent months, further intensifying the battle for control of the capital.
