Machar’s arrest sparks political crisis in South Sudan, threatens fragile peace deal, and raises fears of a return to civil war.
Machar Arrest Sparks Political Crisis in South Sudan
Tensions in South Sudan have escalated following the reported house arrest of First Vice President Riek Machar, raising fears that the country’s peace agreement may collapse.
On March 26, 2025, Machar’s party—the Sudan People’s Liberation Movement-in-Opposition (SPLM-IO)—announced that Defense Minister Angelina Teny and Security Chief Gen. Akol Koor entered Machar’s home with an arrest warrant. Machar, his wife, and two guards were accused of involvement in clashes in Nasir, Upper Nile State, with the White Army militia.

U.S. and U.N. Warn of Escalation
The U.S. Bureau of African Affairs said it was “deeply concerned” and called on President Salva Kiir to reverse the arrest.
The United Nations echoed the concern, warning that ethnic tensions and political instability could lead to a return of the 2013–2018 civil war, which claimed over 400,000 lives.

Opposition Declares Peace Deal Dead
Machar’s party reacted swiftly. SPLM-IO Deputy Chair Oyet Nathaniel Pierino declared the Revitalized Peace Agreement (R-ARCSS) “abrogated.”
“With Machar under arrest, the peace agreement is broken,” Pierino said.
The 2018 accord created the current coalition government. If the SPLM-IO pulls out, South Sudan could fall back into war.

Fragile Coalition Under Threat
Tensions between Machar’s camp and President Kiir’s SPLM faction have been growing. Analysts say the arrest could trigger military defections or armed conflict.
A UNMISS official warned:
“The country is at a breaking point. This could ignite another round of fighting.”

Diplomatic Fallout Widens
In response, the U.S. and EU have downsized their embassies in Juba. Both the African Union (AU) and IGAD have urged calm and called for immediate dialogue.
The Horn of Africa is already unstable. A crisis in South Sudan could worsen conditions in Ethiopia, Sudan, and Somalia, and strain regional humanitarian resources.

With no word yet from President Kiir’s office, pressure is building for Machar’s release and renewed dialogue.
The coming days will determine whether South Sudan preserves peace or slips back into devastating civil war.
