Dujarric said Envoy Lamamra invited both parties to separate “proximity talks” on Thursday morning but “regrettably one of the delegations did not come to the session.”

The UN official did not disclose which side has not arrived.

However, junta leader General Abdel-Fattah Al-Burhan, reaffirmed that there will be no any negotiations with the RSF paramilitary group, according to state-owned Sudan News Agency (SUNA).

“We will not go to the Jeddah negotiating platform until after RSF withdraws and leaves civilian objects and citizens’ homes in all cities of Sudan that they invaded.”

The conflict between national army under General Abdel Fattah Al-Burhan and Rapid Support Force (RSF) of General Mohamed Hamdan Daglo, erupted in April 15, 2023, and has killed tens of thousands, displaced millions and triggered one of the world’s worst humanitarian crises.

Fighting continues daily in several parts of Sudan, with both sides accused of war crimes including the deliberate targeting of civilians, indiscriminate shelling of residential areas and blocking humanitarian aid.

 The United Nations said the country is experiencing one of the worst humanitarian disasters in recent memory and the largest internal displacement crisis in the world.

In October 2023, the warring parties accepted an invitation to resume United States and Saudi Arabia-brokered negotiations in Jeddah and held talks to end the war.

But the Jeddah peace efforts were immediately dealt a blow after the Sudanese army pulled out of the negotiations – accusing the RSF of violating the humanitarian ceasefire and failing to implement the commitments it had made during the negotiations.
