In 2011, a second war broke out between the SPLM-N and the Sudanese government. The UN must leave the areas controlled by the rebels.
In 2019, the establishment of the transitional government enabled the World Food Program (WFP) to regain access to these regions. Its main action is to provide meals to students in order to encourage parents to send their children to school.
At the end of May, representatives of other UN agencies visited the Nuba Mountains. In the absence of a peace agreement, aid continues to flow through South Sudan. Exchanges with the two regions administered by the SPLM-N remain prohibited.
