The current conflict in Sudan, with its rapid escalation and large-scale violence, stands out among recent crises for the severity of its humanitarian impact. Despite being overshadowed on the international stage by the wars in Gaza and Ukraine, Sudan is the scene of the world's fastest growing displacement crisis, mass atrocities, and dire humanitarian needs. The longstanding humanitarian presence in the country was completely disrupted by the sudden escalation of violence in April 2023, with national aid workers displaced, offices and facilities looted, and international staff evacuated. The coordinated aid response has since struggled to scale up sufficiently due to ongoing insecurity, logistical obstacles, political interference, and stringent constraints imposed by parties to the conflict, including denial of visas for staff and restrictions on transporting aid supplies.
