A year into Sudan's civil war, Iranian-made armed drones have helped the army turn the tide of the conflict, halting the progress of the rival paramilitary Rapid Support Force and regaining territory around the capital, a senior army source told Reuters.
Six Iranian sources, regional officials and diplomats - who, like the army source, asked not to be identified because of the sensitivity of the information - also told Reuters the military had acquired Iranian-made unmanned aerial vehicles (UAVs) over the past few months.
The Sudanese Armed Forces (SAF) used some older UAVs in the first months of the war alongside artillery batteries and fighter jets, but had little success in rooting out RSF fighters embedded in heavily populated neighborhoods in Khartoum and other cities, more than a dozen Khartoum residents said.
In January, nine months after fighting erupted, much more effective drones began operating from the army's Wadi Sayidna base to the north of Khartoum, according to five eyewitnesses living in the area.
The residents said the drones appeared to monitor RSF movements, target their positions, and pinpoint artillery strikes in Omdurman, one of three cities on the banks of the Nile that comprise the capital Khartoum.
"In recent weeks, the army has begun to use precise drones in military operations, which forced the RSF to flee from many areas and allowed the army to deploy forces on the ground," said Mohamed Othman, a 59-year-old resident of Omdurman's Al-Thawra district.
The extent and manner of the army's deployment of Iranian UAVs in Omdurman and other areas has not been previously reported. Bloomberg and Sudanese media have reported the presence of Iranian drones in the country.
The senior Sudanese army source denied that the Iranian-made drones came directly from Iran, and declined to say how they were procured or how many the army had received.
The source that while diplomatic cooperation between Sudan and Iran had been restored last year, official military cooperation was still pending.
Asked about Iranian drones, Sudan's acting foreign minister Ali Sadeq, who visited Iran last year and is aligned with the army, told Reuters: "Sudan did not obtain any weapons from Iran."
The army's media department and Iran's foreign ministry did not respond to requests for comment.
A regional source close to Iran's clerical rulers said Iranian Mohajer and Ababil drones had been transported to Sudan several times since late last year by Iran's Qeshm Fars Air. Mohajer and Ababil drones are made by companies operating under Iran's Ministry of Defense, which did not immediately reply to a request for comment.
