An air strike in Sudan’s capital, Khartoum, killed seventeen people, including five children, according to officials.
The Saturday strike in the densely populated Yarmouk district destroyed 25 homes.
It came just a day after a top army general threatened to intensify attacks on the paramilitary Rapid Support Forces.
Fighting broke out in mid-April between the Sudanese army and the RSF as a result of a vicious power struggle within the country’s military leadership.
Early in June, the RSF declared complete control of Yarmouk, a district of the capital that houses an arms manufacturing facility.
Precise figures on the number of people killed in the fighting are difficult to come by, but the figure is thought to be well over 1,000, including many civilians caught in the crossfire.
According to the UN, approximately 2.2 million people have been internally displaced within the country, with more than 500,000 seeking refuge in neighboring countries.
Several ceasefires have been declared in order to allow people to flee the fighting, but they have not been enforced.
According to the RSF, the recent attack targeted civilians in the Mayo, Yarmouk, and Mandela areas. The army has not responded.
Hours later, the warring factions agreed to a 72-hour ceasefire beginning on Sunday at 06:00 (04:00 GMT). Similar ceasefires have not been observed in the past.
Tens of thousands of civilians have fled across the border into neighboring Chad since the fighting began.
Doctors and hospitals in the area have been overburdened and are struggling to keep up. The conflict has also rekindled a two-decade-old conflict in Sudan’s western Darfur region.
