A Sudanese paramilitary force targeted the country’s capital and its main airport on Thursday with drones, just a day after the first passenger flight in two years landed in the city, according to military officials and local media. The attack by the Rapid Support Forces came as the group seeks to maintain pressure against Sudan’s military while the deadlocked conflict grinds on. The Sudanese military intercepted the drones, which caused no damage, said a military official who spoke on condition of anonymity since he was not authorized to speak to journalists.
