South Sudan Vice President on trial for murder and treason

South Sudan’s Vice President Riek Machar is on trial for murder, treason and crimes against humanity, raising concerns about the country’s fragile peace and its unity government. The proceedings began with a special court session in Juba, where Machar and 20 co‑defendants—including Petroleum Minister Puot Kang Chol—appeared before the judges. The charges stem from violent clashes in Nasir earlier this year involving the Nuer‑dominated White Army militia.

Machar, who has been under house arrest since March, made a rare public appearance at the trial. His detention and the case have significant implications for the peace process and the unity government created under the 2018 peace agreement that ended a five‑year civil war responsible for more than 400,000 deaths. Yet the trial threatens to derail that process and destabilise the country ahead of the 2026 presidential elections.

Civil‑society groups are demanding transparency and oversight, criticizing the government’s decision to limit media access. Omara Joseph, Advocacy and Protection Officer at the South Sudan Human Rights Defense Network, stressed the need for international actors to apply pressure to ensure accountability and openness. Restrictions on media have reinforced perceptions that the trial is politically motivated and unlikely to be impartial.

The proceedings have also reignited ethnic tensions between Machar’s Nuer base and President Salva Kiir’s Dinka supporters. Their rivalry dates back to the 1990s, and despite sharing power in a unity government, relations remain strained. Analysts warn that the case against Machar appears to be a pretext for a political power struggle that could plunge the country back into conflict.

The stakes are high not only for Machar and his allies but also for South Sudan’s future. The nation’s leaders must prioritise national unity and pursue a peaceful resolution. With the unity government in disarray, the trial risks undoing years of progress and further destabilising the country. International attention will closely monitor the outcome and its implications for South Sudan’s fragile peace and unity government.
