6 August 2014 - A senior UN peacekeeping official today warned that South Sudan is now on the brink of a humanitarian catastrophe and protracted internal conflict after just three years of independence,

Briefing the Security Council, Assistant Secretary-General for UN Peacekeeping Operations Edmond Mulet urged the international community to “caution [all parties] with one voice on the consequences of impeding the peace process”.

An estimated 1.5 million people have been uprooted in fighting that started with a political impasse in mid-December 2013 between President Salva Kiir and former Vice-President Riek Machar. The conflict also sent nearly 100,000 civilians fleeing to UN bases around the country.

"This is a man-made crisis and those responsible for it have been far too slow in resolving it,” Mr. Mulet said. “Both sides continue to believe they can achieve more through the pursuit of a military option.”

“The scale of humanitarian operations in South Sudan has reached the point that it now constitutes the biggest aid operation inside any single country. However, the capacity and funding of the humanitarian operation falls far short in the face of overwhelming needs.”

Later in the day, Secretary-General Ban Ki-moon condemned in the strongest terms the recent killing of five South Sudanese employees of humanitarian non-governmental organizations in Maban County, Upper Nile state and extended his deepest condolences to their families.

He demanded that relevant authorities conduct a full investigation into these tragic events and called on all armed forces in South Sudan to keep relief personnel and civilians safe from harm.

There is no military solution to the crisis in South Sudan, Mr. Ban said, emphasizing that all parties must immediately cease their military operations to find a peaceful resolution to the conflict.

The Secretary-General welcomed the resumption on 4 August of talks in Addis Ababa under the auspices of the Intergovernmental Authority on Development (IGAD), urging all parties to engage in a meaningful dialogue and advance the political process.

He added that the visit of the UN Security Council to South Sudan in August “will bring international attention to the dire humanitarian situation as well as the plight of the South Sudanese people”.

Some 3.9 million civilians are facing alarming levels of food insecurity, amidst growing concerns of a famine. Meanwhile, among the more than million people have been internally displaced by violence, some 434,000 have fled across borders. Up to 50,000 children are at risk of dying as a consequence of acute malnutrition this year alone. And the cholera epidemic continues to grow with more than 5,300 cases and 115 deaths.

While humanitarian assistance has reached some 2.4 million people, aid efforts have been hampered by insecurity, obstructed access, and insufficient funding. Mr. Mulet warned that the deteriorating humanitarian situation carried with it security implications as communities began to compete for diminishing resources.

To make the situation even worse, militia are targeting aid workers. On Monday, five South Sudanese humanitarian workers of Nuer ethnicity were killed by a community-based self-defense militia calling itself the Mabanese Defence Forces.

Recent fighting in Upper Nile State has also forced UN humanitarian personnel to seek shelter at UN agency compounds. Non-essential UN personnel are currently being airlifted from the area, which will delay and hamper delivery of much-needed relief.

UNMISS is currently hosting nearly 100,000 internally displaced persons (IDPs) at its sites. Conditions there are quickly becoming “extremely challenging,” said Mr. Mulet.

He noted that heavy rains had severely flooded large areas, exacerbating the health and sanitation situation. In addition, several incidents had compromised the safety of UN personnel there.
