JUBA, South Sudan (AP) — At least 36 humanitarian workers and contractors have been killed in South Sudan since January, surpassing the 31 killed in all of 2025, as violence persists in the country that’s one of the most dangerous for aid workers, the U.N. humanitarian coordinator there said Wednesday.

“These are not just statistics,” Ramanathan Balakrishnan said in a statement marking World Humanitarian Day, adding: “Every killing must be investigated, and those responsible held accountable. The continued loss of humanitarian personnel, overwhelmingly South Sudanese nationals, is unacceptable.”

More than 450 incidents of violence against humanitarian workers and assets were reported between January and July, more than double the number recorded during the same period last year, according to the U.N. Mission in South Sudan.

Renewed fighting between government forces and opposition fighters has forced aid organizations to relocate from some areas, further restricting access to vulnerable communities in a country of about 12 million people that has struggled with both conflict and the effects of climate change since independence from Sudan in 2011.

Humanitarian organizations are calling on the South Sudan government and all parties to the 2018 peace agreement meant to end civil war to protect aid workers, investigate attacks and ensure safe and unhindered access to people in need.

Around 10 million people are expected to need humanitarian assistance this year, including more than 7.5 million facing high levels of acute food insecurity, according to the U.N.

Last week, the U.N. refugee agency and World Food Program warned that more than 650,000 refugees and asylum seekers in South Sudan risk losing access to lifesaving food, nutrition and other assistance because of severe funding shortages.
