South Sudan’s army has launched a major military operation against opposition forces after recent territorial losses. Army spokesman Lul Ruai Koang announced Operation Enduring Peace on Sunday, ordering civilians to evacuate three counties in Jonglei state immediately. Aid groups must leave within 48 hours. The operation aims to recapture towns seized by opposition forces and reestablish law and order. This announcement follows a video of a senior commander urging troops to kill civilians, sparking condemnation from the U.N. and others. The conflict marks a resurgence of violence in a country still recovering from a five-year civil war.
