Speaking in Port Sudan, the country's de facto capital, Abdel Fattah al-Burhan said the new administration -- described as either a "caretaker government" or a "war government" -- would be composed of "independent" experts.

"We are seeking to form a government in the coming period that will complete the tasks of transition," Burhan said.

He added that its main objective would be to help "accomplish the remaining military tasks... and cleanse all of Sudan" of the paramilitary Rapid Support Forces (RSF).

Burhan also signalled that the government would lay the groundwork for a broader political transition, preparing the country for elections.

He said a constitutional document would be approved before appointing a prime minister, pledging not to "interfere in his tasks or duties".

The leader announced a cabinet reshuffle in November, replacing four ministers, including those for foreign affairs and media.

Since April 2023, Sudan has been locked in a devastating war between Burhan and his former ally, Mohamed Hamdan Daglo, leader of the RSF.

In his speech on Saturday, Burhan ruled out negotiations with the paramilitary group unless its forces withdrew from Khartoum, West Kordofan in the south and Darfur in the west, and regrouped in "designated locations."

The army has in recent weeks won back large swathes of the capital Khartoum and its surroundings, after nearly two years of RSF control.

The conflict has killed tens of thousands, displaced over 12 million and plunged the country into "the biggest humanitarian crisis ever recorded", according to the International Rescue Committee.
