The number of people internally displaced in Sudan due to conflict could soon exceed 10 million, the United Nations migration agency said on Friday, in the world’s largest displacement crisis.

Fighting broke out in the capital Khartoum in April 2023 and quickly spread across the country, reigniting ethnic bloodshed in the western Darfur region and forcing millions to flee.

“How much suffering and loss of life must the people of Sudan endure before the world takes notice? Isn’t 10m internally displaced enough to compel urgent global action?” said Mohamed Refaat, Sudan Chief of Mission for the International Organisation for Migration (IOM).

“Every one of those 10m displaced life represents a profound human tragedy that demands urgent attention.”

The IOM recorded 9.9m people internally displaced across Sudan this week. Prior to the war, there were already 2.8m internally displaced people, according to the IOM.

In total, about 12m people have been forced to flee their homes, with more than 2m crossing into neighbouring countries, including Egypt and Chad.

Refaat said that more than half of the internally displaced people in Sudan were women and a quarter of them were children under five.

He said aid agencies were struggling to keep up with the rising needs. “Funding shortfalls are impeding efforts to provide adequate shelter, food and medical assistance,” Refaat said.

“Serious concerns are mounting about the long-term impact of displacement on Sudan’s social and economic fabric.”

UN agencies have warned that Sudan was at “imminent risk of famine”, with around 18m people acutely hungry, including 3.6m children who are acutely malnourished.
