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.
