A wave of drone strikes targeted key infrastructure and military sites near Sudan’s army-controlled capital on Tuesday, abruptly ending a period of relative calm, witnesses and officials said.

Strikes hit a power station, a weapons factory and an oil refinery near Khartoum, witnesses at the sites said on condition of anonymity, while a military source said an air base had also been targeted.

The assault came months after the military ousted the paramilitary Rapid Support Forces from the area in May, a key battleground in the war that erupted in April 2023.

It came as the army-backed government pressed a major reconstruction bid in the Khartoum area, after millions of people fled fighting in the city earlier in the conflict.

The attacks occurred at around 5 a.m. (3 a.m. GMT), with witnesses telling Agence France-Presse (AFP) by phone, on condition of anonymity, that they had seen strikes hit the al-Jaili oil refinery, the al-Markhiyat substation in Omdurman and the Yarmuk weapons factory.
