ABÉCHÉ – Nearly 400 Sudanese refugees are crossing into Chad each day, as fighting, airstrikes, drone attacks and worsening humanitarian conditions drive a renewed surge in displacement, according to the U.N. refugee response coordinator for the Sudan crisis.

The U.N. official said refugee arrivals had increased roughly 20-fold in recent months, with people continuing to flee conflict, aerial bombardment, drone attacks, violence and persecution.

He said around 55,000 new refugees had arrived in Chad since the beginning of 2026.

The latest arrivals add to the large number of Sudanese who have crossed into Chad since the war began in April 2023.

According to figures cited by the official, Chad has received around one million Sudanese refugees since the start of 2023, in addition to roughly 400,000 refugees who had already been living in the country since earlier conflicts dating back to 2003.

The official said he had met newly arrived refugees who described fleeing fighting and insecurity inside Sudan.

He warned that the displacement crisis was being compounded by climate-related pressures, including water shortages and below-average rainfall, which are increasing the vulnerability of both displaced populations and host communities.

The U.N. official praised Chad for continuing to receive Sudanese refugees despite the growing strain on communities and public services.

The continuing influx comes as Sudan’s war deepens one of the world’s largest displacement crises, with millions of people uprooted inside the country and across its borders.

Neighboring countries hosting Sudanese refugees are also facing growing pressure to provide food, clean water, shelter, health care and other essential services.

Humanitarian agencies have repeatedly warned that limited funding is constraining their ability to meet rising needs as more people cross borders in search of safety.
