The United Nations Mission in South Sudan (UNMISS) has announced the death of its head, Nicholas Haysom, describing his passing as a great loss to the mission and the country.
In a statement released in Juba on 19 March 2026, UNMISS said Haysom, who served as the Special Representative of the Secretary-General, died after years of distinguished international service.
Haysom was appointed to lead UNMISS in January 2021 by António Guterres, at a critical time when South Sudan was implementing its fragile peace agreement following years of conflict. He brought decades of experience working with the United Nations in countries such as Sudan, Somalia, Afghanistan, and Iraq.
During his tenure, Haysom played a key role in supporting the implementation of the revitalized peace agreement, often engaging political leaders and stakeholders to reduce tensions and encourage dialogue. Under his leadership, UNMISS intensified efforts to protect civilians, promote human rights, and support the country’s transition toward democratic governance.
A skilled mediator and constitutional expert, Haysom was widely recognized for his diplomatic approach in navigating complex political situations. He consistently emphasized inclusivity, urging South Sudanese leaders to prioritize the interests of citizens and work toward lasting peace and stability.
UNMISS noted that Haysom firmly believed the international community should stand alongside the people of South Sudan in their nation-building efforts. He remained committed to advancing a peaceful, inclusive, and democratic transition throughout his time in office.
Before his international career, Haysom was an anti-apartheid activist and human rights lawyer in South Africa, where he built a reputation for defending justice and the rule of law—values that shaped his work across the globe.
Colleagues described him as a principled and dedicated leader whose work inspired UN peacekeepers and civilians alike.
UNMISS extended its condolences to his family, colleagues, and the people of South Africa, saying his legacy will continue to inspire efforts toward peace and stability in South Sudan.
