South Sudan's army chief, General Paul Nang Majok, has ordered soldiers to crush a rebellion within seven days. The rebellion, led by the Sudan People's Liberation Army in Opposition (SPLA-IO), has captured several areas in Jonglei state, threatening the town of Bor, just two hours from the capital, Juba. Bor is strategic as a gateway to the capital and was the first town taken by rebels in the 2013-2018 civil war. SPLA-IO leader Riek Machar, who is suspended as First Vice-President, is on trial for murder, treason, and crimes against humanity, charges he denies. Fighting has raised fears of a return to full civil war after a peace deal in 2018 ended years of conflict that killed nearly 400,000 people. Reinforcements from the South Sudanese army, supported by Ugandan soldiers, are moving to retake rebel-held areas. The Ugandan troop numbers are unclear, with reports of about 4,000 soldiers. General Nang Majok told his troops, "We brought you here for a mission. I am giving you seven days only to finish the mission – to crush the rebellion in those areas and recapture them." Analysts say the SPLA-IO threats to attack Juba aim to pressure the government for Machar’s release. Recently, President Salva Kiir removed Machar’s wife, Angelina Teny, from her minister post, stirring more political tension. The UN peace mission in South Sudan, Unmiss, urged an immediate stop to hostilities. Kiki Gbeho, acting head of Unmiss, called on leaders to "immediately cease hostilities, de-escalate tensions, and advance reconciliation and peace through inclusive dialogue under the framework of the peace agreement." The UN Commission on Human Rights in South Sudan warned of repeated airstrikes in Jonglei, which have killed civilians and destroyed homes and facilities, causing mass displacement. Chair Yasmin Sooka expressed deep alarm at the growing violence. SPLA-IO's acting chief of staff, Lieutenant General Peter Thok Chuol Luak, warned Juba residents about imminent attacks and advised evacuation or staying indoors. State Governor Emmanuel Adil Anthony told citizens to ignore these threats. The situation remains tense as forces prepare for possible clashes near the capital.
