While the majority of people have been displaced internally, hundreds of thousands have fled to neighboring countries too.

More than 1 million people have been displaced by five weeks of fighting in Sudan, including a quarter of a million refugees, according to the United Nations refugee agency.

The situation is dire, with tens of thousands of people trapped indoors and running out of essential supplies such as food, water, and medicine. Health services are struggling, with several hospitals closing due to a shortage of medical supplies. As a result, almost one million people have fled their homes, seeking refuge in other states in Sudan and neighbouring countries.

The latest figure includes some 843,000 people displaced internally and around 250,000 people who have fled across Sudan’s borders, the spokesman told a Geneva briefing.

Egypt has seen the highest number of Sudanese refugees arrive in the country with 110,000 people there, Saltmarsh added. Chad, South Sudan and Ethiopia are other countries with large numbers.

"Many of those who have approached us are in a distressed state having been exposed to violence or traumatic conditions in Sudan, and having suffered arduous journey," Saltmarsh said in the briefing.

General Abdel Fattah Burhan sacked General Mohamed Hamdan Dagalo, widely known as Hemedti, as his deputy on the Sovereign Council with immediate effect.

As the head of the Council, Burhan appointed former rebel leader Malik Agar as the deputy on the Council.

Sudan spiraled into chaos after the two powerful groups of the country; the army led by Burhan and the paramilitary Rapid Support Forces (RSF) led by Hemedti, turned on each other.

The men were allied in the 2021 coup and the toppling of long-time dictator Omar al-Bashir in 2019.

That led to the establishment of a joint civilian-military Sovereign Council headed by Burhan that was supposed to rule Sudan until elections, set for 2023.

But the integration of the armed forces or how the RSF would be integrated into the military led to tensions between the generals.

Talks for a democratic transition halted after the 2021 coup, but the armed forces and the RSF under international pressure signed a preliminary deal in December to chart a path to democratic transition.

Still, the issue of having control over fighters and weapons wasn't resolved and the tensions ultimately led to a full-blown crisis on April 15.

IRC staff at the borders with Sudan have reported thousands of refugees living in makeshift tents with limited access to clean water and sanitation.
