At least 169 people were killed when dozens of armed youth launched a surprise raid on Abiemnom county in South Sudan's northern Ruweng Administrative Area early Sunday. The attackers, who originated from Mayom County in neighboring Unity State, struck around 4:30 a.m. local time while residents slept, catching local forces off guard.

James Monyluak Mijok, information minister for Ruweng Administrative Area, reported that 90 of the victims were civilians, including children, women and the elderly, while 79 were members of regional security forces, such as police and soldiers. Among the dead were senior officials, including the county commissioner and executive director. An additional 50 people were wounded, many treated in the neighboring Abyei area. Due to the high casualty count and security risks, all 169 bodies were buried in a mass grave Monday, though officials warned the toll could rise as some remain missing.

The fighting lasted three to four hours, with assailants setting homes and markets ablaze before government forces regained control. Ruweng officials alleged the attackers were linked to the Sudan People's Liberation Army in Opposition (SPLA-IO), the group of former Vice President Riek Machar, or the White Army militia. The SPLA-IO denied involvement, accusing Unity state authorities of politicizing the incident.

Approximately 1,000 civilians fled to a nearby United Nations Mission in South Sudan (UNMISS) base for protection following the assault. Peacekeepers provided emergency medical care to at least 23 wounded individuals and enhanced security measures. UNMISS officer Anita Kiki Gbeho condemned the violence, stating, "Such violence places civilians at grave risk and must stop immediately." She urged all parties to cease hostilities and pursue dialogue.

The raid underscores escalating communal and political tensions in South Sudan, the world's youngest nation, which has struggled with civil war, poverty and corruption since independence in 2011. A fragile 2018 power-sharing agreement between President Salva Kiir and Riek Machar has deteriorated, particularly after Machar's removal as first vice president last year and his current house arrest in Juba. Recent clashes in Jonglei state have displaced hundreds of thousands and led to the disappearance of 26 Doctors Without Borders (MSF) staff, prompting the group to suspend operations in affected areas. The United Nations has repeatedly warned of the risk of full-scale civil war returning.
