Sudan's armed forces agreed to extend the ceasefire, which was proposed for an additional 72 hours, to take effect from the expiry date of the current truce.

In a statement, the General Command of the Armed Forces said that the Saudi and American sides contributed to calming the situation, and the ceasefire was extended to create appropriate conditions to evacuate residents of various nationalities.

The statement added that the armed forces hope that the forces will abide by the ceasefire and avoid violating it "by bombing the military institutions and sites of our forces, sabotaging vital facilities, and endangering the lives and property of citizens."

On the last day of the fourth ceasefire, clashes erupted at several points in Khartoum and plumes of smoke rose in the vicinity of the presidential palace in Khartoum, coinciding with the overflight of warplanes. 

The Rapid Support Forces said that the army targeted its camp in the Kafouri area in Khartoum, using air strikes and artillery. Mohammed Hamdan Dagalo (Hemedti)'s forces also brought in additional forces from the western and southwestern regions, in preparation for upcoming confrontations.

For its part, the White House ruled out any improvement in the situation and urged US citizens to leave the country within 48 hours.

In a statement, the White House called on the Sudanese army and the Rapid Support Forces (RSF) to fully comply with the ceasefire agreement and extend it.

The Pentagon said on Thursday that only a few Americans seek to leave Sudan at this time.
