Drone attacks by Sudan’s RSF paramilitary forces disrupted the planned reopening of Khartoum International Airport on Wednesday, more than a year and a half after it was closed due to civil war.

Explosions and drone strikes were reported across the capital, delaying domestic flights intended to mark government control of the city, which has been largely calm since the Sudanese Armed Forces (SAF) pushed RSF forces out in March.

The airport reopening was a key step toward restoring international flights and encouraging civilians to return, as the government also undertakes reconstruction and plans to move ministries back to Khartoum, CBS News has reported.

Meanwhile, the RSF continues heavy fighting in Darfur, particularly around the besieged city of El-Fasher, intensifying Sudan’s ongoing humanitarian crisis.
