Millions of people uprooted by Sudan's civil war risk being left without emergency shelter as humanitarian funding and stockpiles run low, United Nations agencies have warned.

The UN refugee agency and the International Organization for Migration said about 15.4 million people across Sudan urgently need emergency shelter and basic household items. Funding shortages mean partners can prioritise help for only about 10 percent of those in need. So far only around 936,000 people have received assistance, leaving a vast gap between need and supply.

In a joint statement on Friday the agencies said they were working with local partners to keep shared supply lines open, pre position stocks in priority areas and deliver aid where the need is greatest. They stressed those efforts cannot continue without predictable and flexible funding.

War between the Sudanese army and the paramilitary Rapid Support Forces since 2023 has created the world's largest displacement crisis. About 8.6 million people are displaced inside Sudan and more than 4.6 million have fled across borders. More than 5.2 million people have also returned to home areas, often finding houses, infrastructure and basic services destroyed.

From Khartoum, the IOM chief in Sudan said warehouses that distributed more than 40,000 tonnes of supplies this year are now completely empty. He warned that internal displacement could rise again despite recent returns and said agencies had already scaled back plans because money is short. Officials argued that a safe place to sleep and basic household goods are the first step toward safety and dignity for families repeatedly forced to move, especially women and children at heightened risk.
