Violence between South Sudan government forces and opposition fighters has displaced about 280,000 people since December. Most affected are in Jonglei state, where 235,000 have fled fighting. Floating in desperate conditions, families like Ajok Ding Duot’s rely on wild nuts and fruits for survival. "We’re in darkness. It’s only ever the humanitarian organisations who help," Duot told Al Jazeera. The United Nations warns nearly 10 million South Sudanese need urgent aid. Yet humanitarian work is blocked by attacks, looting, and road restrictions. The World Food Programme stopped help in Upper Nile's Baliet county after repeated assaults on its convoys. Doctors Without Borders (MSF) reports 10 attacks on its medical facilities in the last year. One hospital in Jonglei was hit by a government airstrike, forcing closure and evacuations. MSF says 250,000 people lost access to healthcare. "We are in constructive dialogue with the government... to allow access," said MSF’s Gul Badshah. Meanwhile, reports of sexual violence against fleeing women are rising. Al Jazeera correspondent Malcolm Webb shared stories of rape and near assaults by soldiers. The UN chief Antonio Guterres condemned the bloodshed on Sunday. He urged all sides to stop fighting, protect civilians, and ensure safe delivery of aid. "Civilians continue to bear the brunt of the conflict," said Guterres, calling for dialogue and peace.
