Amnesty International expressed concern April 1 about the lack of political will in South Sudan to address ongoing violations of international human rights law amid escalating violence from both internal and cross-border actors. Reports indicate mounting attacks on civilians, political repression, and the increasing risk of a wider war.

South Sudanese troops have deployed around the house of Vice President Riek Machar and arrested officials from his SPLA-IO party, marking one of the most serious threats yet to the peace deal that Machar's group signed with President Salva Kiir in 2018. The arrests follow reports of clashes in northeastern Upper Nile state between the national army and the ethnic Nuer militia known as the White Army, which was allied to Marchar during the 2013-2018 civil war. Machar's spokesperson said they do not know why their officials have been detained, but the information minister accused them of collaborating with the White Army. The International Crisis Group’s senior analyst on South Sudan told Reuters that a delicate balance of power among political elites is now "at risk of collapsing," while the UN and regional bodies warned of "widespread violence" in Upper Nile. Tensions have been mounting since the government's decision last year to postpone long-overdue elections, a delay that critics called a failure to implement the 2018 agreement—which has itself been blamed for fuelling instability. Commanders and politicians compete for power in a transitional government based in the capital, Juba, by fighting local wars in the peripheries.

The United Nations on Dec. 20 raised alarms over the worsening humanitarian situation in El Fasher, capital of Sudan's North Darfur state, where a months-long siege by the Rapid Support Forces (RSF) has devastated lives and infrastructure. According to the UN Human Rights Office (OHCHR) report, more than 782 civilians have been killed and 1,143 injured since May 2024, with thousands more trapped in the city. Testimonies gathered by the OHCHR reveal the indiscriminate nature of the attacks, including the deliberate targeting of civilian areas and healthcare facilities. Accounts from survivors depict a city under constant bombardment, with residents forced to abandon their homes amid extensive looting and violence by RSF forces.

The International Rescue Committee (IRC) declared on Dec. 11 that Sudan is currently experiencing the worst humanitarian crisis ever recorded. The report states that approximately 30.4 million people—over half of Sudan's population—are in urgent need of humanitarian assistance, a staggering figure that accounts for 10% of all people globally requiring aid, despite Sudan representing less than 1% of the world's population. Health services have been critically impacted, with more than 70% of healthcare facilities nonfunctional and widespread outbreaks of diseases like cholera and malaria threatening already vulnerable populations.

A panel of UN rights experts on April 3 named senior officials and military leaders in South Sudan who they say warrant criminal prosecution for their part in grave atrocities against civilians. A year-long investigation by the UN Commission on Human Rights in South Sudan details the involvement of both government and rebel leaders in widespread extrajudicial killings, as well as rape and sexual slavery.

Among the long list of ostensibly local conflicts that have broken out in South Sudan since a national peace deal was inked in 2018, analysts say the current violence involving Nuer and Shilluk militias in Upper Nile state ranks with the deadliest. Thousands of people have been uprooted since mid-November and there are concerns of an imminent attack on Kodok—a town hosting more than 10,000 displaced Shilluk. The UN's peacekeeping mission has been encouraged to step up protection duties, but Nuer forces have reportedly encircled Kodok and cut off escape routes, including to the nearby UN protection camp in Malakal. Though clashes are occurring along communal lines, they were triggered by internal tensions within a splinter group of the country's main opposition movement, the SPLA-IO. Simon Gatwech (a Lou Nuer) and Johnson Olony (a prominent Shilluk) defected from the group last year before turning on each other. President Salva Kiir has said he "cannot stop" the fighting, though observers say his regime benefits from pitting the feuding factions against each other.

The Supreme Court of Sweden on Nov. 10 ruled that the trial of Alex Schneiter, a Swiss citizen and former CEO of Lundin Oil charged in connection with war crimes in Sudan, may proceed in the Swedish courts. While Lundin Oil is a Swedish-based company, Schneiter claims that he cannot be tried in Sweden because he is neither a citizen nor a resident. This claim was rejected by the lower courts, and now by the high court. The Supreme Court held that Schneiter's alleged crimes are subject to "universal jurisdiction," which allows anyone to be prosecuted anywhere in the world for serious international crimes. Justice Johan Danelius concluded: "The fact that the defendant is not [resident] in Sweden does not constitute an obstacle to Swedish jurisdiction, provided that the connection to Sweden in other respects is sufficient." The criminal case will now proceed in the Stockholm District Court.

Kenya is set to deploy a battalion of soldiers to eastern Democratic Republic of Congo as part of a regional military response to advancing M23 rebels. Kenya will command the new East African force, which will include troops from Burundi, South Sudan and Uganda. A notable absentee from this intervention will be Rwanda: Congo accuses Kigali of supporting M23, and tensions are soaring. In the past weeks, M23 has dramatically expanded the territory it controls, forcing UN peacekeepers to abandon a strategic base at Rumangabo, and closing in on the key city of Goma. In a region with a history of foreign meddling—in which more than 120 rebel groups operate—the East African deployment is distrusted. Both Burundi and Uganda already have troops inside Congo pursuing their own interests. It remains unclear how the new East African force will be funded; how it will coordinate with UN peacekeepers (in which Kenya also has a contingent); and what its exit strategy will be. Some are urgently calling for regional dialogue as the solution to Congo's instability, fearing the military option will only make matters worse.
