Iran and the United Arab Emirates have been accused of violating a UN arms embargo by supplying drones to the warring sides of the Sudan civil war.

A BBC investigation has documented the Sudanese Army's use of types of Iranian drones in its war against the Rapid Support Forces (RSF). Evidence has also emerged that the RSF received modified commercial drones from the UAE.

Foreign-made drones prominently changed the course of the war on the ground since their appearance in 2023.

Sudan's armed forces have been fighting the RSF for the last 14 months.

The BBC has contacted the Sudanese army, Iran’s Ministry of Foreign Affairs and Qeshm Fars Air to comment on the allegations that Iranian drones are being used in the conflict but has not had a response.
