UNITED NATIONS, November 6. /TASS/. The armed conflict in Sudan has forced more than 980,000 Sudanese nationals to flee to neighboring Chad since April 2023, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said.

Over the same period, more than 404,000 Chadian nationals have returned to their home country from Sudan. The agency also warned of a worsening humanitarian situation in eastern Chad, citing concerns over food security, access to water and healthcare.

OCHA said that the continued arrival of Sudanese refugees and the return of Chadian nationals are placing growing pressure on resources, basic services and the humanitarian response in eastern Chad. According to the agency, more than 980,399 Sudanese refugees and 404,256 Chadian nationals had arrived in the country between April 2023 and October 15, 2026. The agency described the humanitarian situation in the region as alarming.

OCHA also voiced concern over the precarious access to water and healthcare in eastern Chad. The agency further warned of agroclimatic risks in the region, which affect both people arriving from Sudan and local residents.

More than 668,000 people have experienced acute food insecurity in recent months. OCHA warned that the situation could worsen without emergency assistance, particularly in light of the unfavorable outlook for the 2026-2027 agricultural and livestock season.

The UN also noted that inadequate infrastructure and limited social service capacity make it harder for people to access essential services and further exacerbate existing vulnerabilities.

The armed conflict between the Sudanese army and the rebel Rapid Support Forces (RSF) has been ongoing since April 2023. According to the UN, tens of thousands of people have been killed in the fighting, and around 14 million have been forced to flee their homes.
