Humanitarian operations have been impeded by attacks, looting and restrictions on movement.

Ajok Ding Duot crouches on the dusty floor of a displacement camp in South Sudan’s Lakes state, cracking nuts open one by one.

She and her family of 10 arrived here about two weeks ago, fleeing intensifying fighting between government and opposition forces in neighbouring Jonglei state.

While they have found temporary shelter, Duot said there was hardly anything to eat at the camp. To survive, they rely on these nuts and wild fruits.

“We don’t know anything about what the government is doing. They’re fighting, but we don’t know what the problem is,” she told Al Jazeera.

“We’re in darkness. It’s only ever the humanitarian organisations who help.”

South Sudan has seen renewed fighting in recent weeks between government soldiers and fighters loyal to the Sudan People’s Liberation Army-in-Opposition (SPLA-IO).

The United Nations says an estimated 280,000 people have been displaced by the fighting and air attacks since late December, including more than 235,000 across Jonglei alone.

The UN’s children agency UNICEF also warned last week that more than 450,000 children are at risk of acute malnutrition due to mass displacement and the halting of critical medical services in Jonglei.

Nearly 10 million people need life-saving humanitarian assistance across South Sudan, a country still reeling from a ruinous civil war that killed nearly 400,000 people and displaced millions between 2013 and 2018.

Humanitarian operations, however, have been crippled by attacks and looting, with observers saying both sides in the conflict have prevented assistance from reaching areas where they believe civilians support their opponents.

The UN’s World Food Programme (WFP) suspended its activities last week in Baliet county, in Upper Nile state, following repeated attacks on a convoy carrying humanitarian assistance.

The WFP said the suspension would remain in place until the safety of its staff could be guaranteed and authorities take immediate action to recover the stolen supplies.

Separately, medical humanitarian NGO Doctors Without Borders, known by its French initials MSF, said last week a hospital in Jonglei was hit by a government air attack, marking the 10th attack in 12 months on an MSF-run medical facility in the country.

In addition, the MSF health facility in Pieri, also in Jonglei, was looted by unknown assailants, forcing staff to flee. The organisation said the violence had left some 250,000 people without healthcare, as the NGO had been the only medical provider in the area.

MSF said the targeted attacks on its facilities have forced the closure of two hospitals in the Greater Upper Nile and the suspension of general healthcare activities in Jonglei, Upper Nile and Central Equatoria states.

On Sunday, UN chief Antonio Guterres “strongly” condemned the escalating violence in the country and warned that civilians continue to bear the brunt of the conflict.

In a statement, the secretary-general called on all parties “to immediately and decisively halt all military operations, de-escalate tensions through dialogue, uphold international law, protect civilians, and ensure safe and sustained humanitarian access and the security of aid workers and United Nations peacekeeping personnel and their assets”.

María Corina Machado said Monday that a Venezuelan opposition leader was seized in Caracas shortly after being released from jail.

Machado wrote in a post on X that Juan Pablo Guanipa, a key ally, was kidnapped by heavily armed men in civilian clothing in the Los Chorros area of the capital.

“We demand his immediate release,” she said.

Alfredo Romero, the president of the Venezuelan human rights group Foro Penal, said 35 political prisoners were released on Sunday, including Guanipa, who was initially arrested in May.

Reuters reported that Venezuelan authorities were seeking court approval to place Guanipa under house arrest.

The country’s Public Ministry alleged that he violated the terms of his release but provided no additional details and did not say whether he had been re-arrested.

Guanipa’s Primero Justicia party said on X that he was forced into a silver Toyota Corolla during the incident.

“We hold Delcy Rodríguez, Jorge Rodríguez, and Diosdado Cabello responsible for any harm to Juan Pablo’s life,” the party wrote. “We call on the international community for the immediate release of Juan Pablo Guanipa and for an immediate and unconditional end to the persecution of the opposition.”

The U.S. State Department did not immediately respond to Fox News Digital’s request for comment.

In late January, President Donald Trump said Venezuela was releasing political prisoners at a “rapid rate,” praising the move as a “powerful humanitarian gesture” by the country’s leadership.

An estimated 687 political prisoners remain in custody in Venezuela as of Feb. 2, according to Foro Penal.
