Sudanese Rapid Support Forces on Thursday launched several drone strikes on the northern town of Merowe, targeting a major dam in army-held territory, the army and other sources said.
Drones "targeted the army headquarters, the airport and the Merowe Dam", an army statement said, adding that it had intercepted the attacks that it blamed on the RSF.
A source from the intelligence service said seven projectiles had been fired, while an AFP journalist in the area heard 10 explosions.
Witnesses meanwhile counted more than two dozen explosions between midnight and dawn, adding that the town, about 350 kilometers (220 miles) north of Khartoum, was plunged into darkness after a full power cut.
The RSF has increasingly resorted to drones over the past months as its war with the army grinds on.
The RSF have repeatedly targeted both military and civilian facilities, intensifying its attacks on the capital Khartoum in October and the wartime seat of government in Port Sudan during the spring.
In late October, the RSF captured El-Fasher, the last army stronghold in the vast western Darfur region, consolidating its hold over the area.
Since the fall of El-Fasher, fighting has shifted to the neighboring Kordofan region, a strategic area bridging the west of the country with the capital.
According to the International Organization for Migration, 90,000 civilians have fled El-Fasher since it fell into RSF control.
