The rebel Justice and Equality Movement and the Sudan people's Liberation Movement-North both issued statements announcing the downing of an Iranian-manufactured craft, the Sudan Tribune reported Wednesday.
Sudan's Armed Forces admitted losing one of its drones in the disputed area of Jau but attributed the downing to a technical failure.
A spokesman for the rebels called for action by the international community.
"It is high time the international community rise up to hold [the] Iranian government responsible for violating international law by constantly meddling in the domestic affairs of the Sudanese people," said Arnu N. Loddi of the Liberation Movement-North.
Loddi said the use of Iranian-made missiles, land mines, drones and heavy military equipment prove Khartoum is continuing its policy of genocide and ethnic cleansing.
