ACI Africa, Mar 29, 2025 / 07:00 am (CNA).

A Catholic bishop in the Africa’s youngest country has directed the people under his care to participate in daily prayers for peace amid testimonies of rising tension in South Sudan and reports of the arrest of the country’s first vice president, Dr. Riek Machar.

“First vice president” is a position that was created in 2015 as part of a coalition agreement. Five more such positions were created in 2020. They are temporary positions to assist during a transition period.

“As we witness rising tensions in South Sudan, I invite our parishes to pray every day for peace,” Bishop Christian Carlassare wrote in a March 26 note obtained by ACI Africa, CNA’s news partner in Africa.

The local ordinary of the Bentiu Diocese in South Sudan, who also serves as the apostolic administrator of the country’s Diocese of Rumbek, directed that “the prayer for peace in South Sudan” be said “at the end of the Mass” and that there be in parishes “a weekly initiative for peace — either Eucharistic adoration or the Way of the Cross.”

Hours after Carlassare’s directive on daily prayers for peace in South Sudan, reports emerged of the arrest of Machar.

“South Sudanese security forces placed first vice president and opposition leader Dr. Riek Machar under house arrest in Juba on Wednesday night amid escalating political tensions, raising fears of a return to civil war,” Radio Tamazuj, an independent daily news service covering current affairs in Sudan and South Sudan, reported on March 26.

According to a March 26 Reuters report, Machar’s party, the South Sudanese People’s Liberation Movement-In Opposition (SPLM-IO), is “trying to locate him after the defense minister and chief of national security ‘forcefully entered’ his residence and delivered an arrest warrant.”

The Reuters report cites a statement from Machar’s SPLM-IO party condemning “a blatant violation of the constitution and the Revitalized Peace Agreement,” which refers to the September 2018 Revitalized Agreement on the Resolution of Conflict in South Sudan that ended a 2013–2018 civil war between armed forces loyal to Machar and those aligned to South Sudan’s president, Salva Kiir.

“The house arrest of Dr. Riek Machar is widely seen as jeopardizing the peace agreement,” Radio Tamazuj reported. The news service quoted Reath Muoch Tang, the acting chairperson of the SPLM-IO’s Committee on Foreign Relations, sharing details of Machar’s house arrest. 

“The security forces came and chased everyone away from the compound, and the minister of defense left, but many security vehicles remained in the compound,” Muoch Tang is quoted as telling Radio Tamazuj, adding: “Technically, Dr. Machar is under house arrest, but the security officials initially tried to take him away.”

In a statement obtained by ACI Africa, the official spokesperson of SPLM-IO, Pal Mai Deng, confirmed “with grave concern” that Machar “has been placed under house arrest.”

“This is an unfortunate move, and this violates the revitalized peace agreement,” Mai Deng said.

“For the sake of South Sudan’s future nationhood and nation-building, the physical security of Dr. Riek Machar is paramount,” said the SPLM-IO spokesperson, who serves as South Sudan’s minister of water and irrigation under the power-sharing agreement. “The region and the international community have the obligation to ensure his safety.”

According to Reuters, foreign governments have cautioned against a renewed civil war in South Sudan “following weeks of escalating tensions that originated in fighting between government troops and a militia that has historically been close to Machar’s forces.”

Earlier, in a media briefing on March 24, the special representative of the secretary-general for South Sudan and head of the United Nations mission in South Sudan, Nicholas Haysom, described the security situation in South Sudan as “dire.”

According to him, efforts to realize lasting peace in the east-central African nation can only succeed if the country’s president and its first vice president, Machar, have the will to engage and especially to “put the interests of their people ahead of their own.”

Meanwhile, in his directive on daily prayers for peace in South Sudan, Carlassare is considering the possibility of having more public prayer for peace.
