The Sudan People’s Liberation Movement in Opposition (SPLM-IO) has announced the dissolution of the 2018 peace deal subsequent to the arrest of its leader, Dr. Riek Machar, the first vice president of South Sudan.

Hon. Oyet Nathaniel Perieno, deputy chairman of the SPLM-IO and first deputy speaker of the national parliament, confirmed in a statement on Thursday that his boss, President Salva Kiir’s rival Machar, was placed under house arrest on Wednesday, March 26, 2025, at 9:46 PM.

The arrest, carried out by senior security personnel from the National Security, Tiger Division, and the South Sudan People’s Defense Forces under President Kiir’s directive, also included Machar's wife, Angelina Teny, Minister of Interior, and his protocol team and close protection guards, signaling the collapse of the peace agreement.

“The arrest and detention of H.E Dr. Riek Machar Teny effectively brings the Agreement to a collapse; thus, the prospect for Peace and Stability in South Sudan has now been put into serious jeopardy,” Oyet stated.

With the government yet to comment on the development, the senior opposition official stated that the arrest ordered by President Kiir represents a breach of commitments, undermines agreements, and reflects a lack of political will to achieve peace and stability in the country.

“Consequently, we would like to declare that with the arrest and detention of H.E Dr. Riek Machar Teny the R-ARCSS, 2018 has been abrogated,” he declared.

Oyet raised concerns about the escalating airstrikes and ground military operations near Juba, targeting cantonment sites and training centers in Wunliet, Aswa, and Rejaf. He urged regional and international intervention to ensure the safety and release of SPLM-IO detainees.

Civil society activists, the United Nations, and the United States have called for restraint and the reversal of the action following reports of the arrest.

The ongoing conflict has raised concerns among observers and citizens about the stability of South Sudan's fragile peace process, with fears that the country may relapse into renewed civil war.
