Sudan's foreign ministry said Tuesday that the United States should designate the paramilitary Rapid Support Forces a "terrorist organization", a day after Washington slapped the same designation on the local branch of the Muslim Brotherhood.
The US designation for the Brotherhood, which will come into effect next week, accused the Islamist group of receiving support from Iran.
Noting that decision, while stopping short of criticizing it, Sudan's foreign ministry said "all groups that violate international humanitarian law and commit terrorism, crimes against humanity, and war crimes in Sudan should be designated as terrorist groups".
The US, it added, should therefore "designate the RSF militia as a terrorist group, given its proven crimes and documented violations of international humanitarian law, including war crimes, crimes against humanity, genocide, and terrorism".
Since 2023, the RSF -- under paramilitary commander Mohamed Hamdan Daglo -- has been at war with the regular army, under Sudan's de facto leader Abdel Fattah al-Burhan.
Burhan has a complex relationship with Islamists, relying on them for political support and fighters, but facing pressure from the US and his allies to distance himself from them.
He has denied having Brotherhood members in his government.
The RSF has been widely accused of mass atrocities, and last month was found by a UN inquiry to have committed "acts of genocide" in Darfur.
Last year, the US issued a similar genocide determination.
The RSF has repeatedly characterized the war as a fight against Sudan's Islamists and the remnants of the ruling system of Islamist-military president Omar al-Bashir, whom Daglo and Burhan helped oust in 2019.
