The experts urged all parties to immediately cease hostilities, ensure safe humanitarian access and create conditions for the voluntary, safe and dignified return of internally displaced persons.

“South Sudan stands at a critical juncture,” the group said in a statement. “All parties must immediately cease hostilities and engage in meaningful dialogue to prevent further escalation of conflict and protect civilians.”

Jonglei State has emerged as the epicentre of the crisis. More than 267 000 people have reportedly been displaced there since the beginning of 2026 alone, according to information cited by the experts.

Women make up the majority of those displaced, while children under 18 constitute a significant proportion of affected communities. Displaced families are facing acute food insecurity, severe shortages of shelter and limited access to healthcare, clean water and other essential services.

The humanitarian situation is being further compounded by conflict and climate shocks, which have disrupted education across wide areas. More than 300 schools have reportedly been affected, leaving around 300 000 learners without access to education.

“The reported destruction of water sources, as well as the looting and burning of homes, hospitals, schools and places of worship, are particularly alarming,” the experts said. “If verified, these acts would constitute serious violations of international humanitarian law and may amount to war crimes.”
