The head of Sudan’s paramilitary Rapid Support Forces said on Thursday that the faction remained ready to implement a nationwide ceasefire in its war with the army and allow for the delivery of humanitarian aid.

Sudan’s de facto ruler said Thursday that he wants to end the war in his country, but he said he will not sit with his rival general unless he withdraws his fighters.

The army recaptured parts of Omdurman from the RSF in a major offensive in February. It lost control of most of the capital to the paramilitary group at the start of the conflict last April and has since been unable to oust it from Khartoum.

The head of Sudan's army said on Thursday that he supported efforts to bring an end to a devastating war in his country as long as they brought an end to the "occupation" of territory by the rival Rapid Support Forces (RSF).

The latest outbreak of fighting comes as nations gathered at the U.N. General Assembly called for an end to the war and for aid to be fast-tracked to millions in need.
