In May, conflict remains the primary barrier to humanitarian access and the delivery of lifesaving assistance, particularly in Upper Nile and Jonglei states, with 39 reported access incidents.Clashes between the SSPDF and armed groups, including airstrikes and ground attacks, disrupted humanitarian operations, destroyed a health facility, and forced the relocation of 28 humanitarian workers due to heightened insecurity. To date, a cumulative figure of 122,081 individuals in Upper Nile, 75,906 in Jonglei, and 30,496 people in Central Equatoria have been displaced in these three states this year. Conflict-related constraints increased across Upper Nile, Jonglei, Central and Western Equatoria, and Western Bahr el Ghazal. In Yei County, critical medical outreach operations were temporarily paused due to the frequent clashes.Criminal activity targeting humanitarian personnel and assets increased across Central Equatoria, Upper Nile, Jonglei, Western Equatoria, and Northern Bahr el Ghazal states. In Central Equatoria, two humanitarian workers were abducted between Yei and Mugwo, with ransom demands made. In Greater Pibor, 7.725 MT of nutrition supplies and drugs were looted by armed youth, depriving 23,080 children under five of malnutrition treatment for three months. Similar incidents occurred in Panyijiar, Unity State, and Longochuk County, Upper Nile State.Bureaucratic impediments too continued to impede delivery. In Renk County, authorities halted NGO recruitment, demanding prioritisation of locals and clearance through the labour office. In Greater Pibor, authorities requested full staff lists from NGOs and companies, including names, roles, gender, and place of origin. Humanitarian missions to Morobo encountered intensified checkpoints and searches, causing delays in critical aid deliveries. Local authorities in Ayod County verbally instructed humanitarian partners to pause their operations.With the onset of the rainy season, river transport has become the most viable option for reaching affected communities in Upper Nile, Unity, and Jonglei states. However, the routes between Bor and Malakal, as well as along the Sobat Corridor, have been severely impacted by the ongoing conflict in the Fangak, Canal/Pigi, and Sobat River areas. These disruptions have significantly hindered the delivery of aid to populations along the Nile and beyond.
