A staggering 10.7 million people are now displaced by conflicts in Sudan, including nine million inside the country, according to new data from the International Organization for Migration (IOM).

The organization is calling for concerted international efforts to urgently scale up humanitarian response to the world's largest displacement.

Of the 10.7 million people displaced, 1.7 million have fled the violence to neighboring countries. The vast majority are Sudanese.

Chad shelters the highest number of Sudanese refugees

Chad hosts the majority of arrivals -- around 37% -- while South Sudan hosts 30% and Egypt 24%. Ethiopia, Libya and the Central African Republic host the remainder.

These arrivals create additional humanitarian needs in a region already in deep crisis.

"As of today, one in every eight internally displaced persons in the world is in Sudan," said Amy Pope, IOM Director General.

"Their needs are overwhelming: dire shortages of food, shelter, healthcare, and sanitation, all combine to place them at heightened risk of disease, malnutrition, and violence," she continued. "Yet the humanitarian response so far is insufficient to meet the dire needs. We cannot turn our backs on the millions of people in need of support."

Armed clashes over the past nine months have uprooted over six million people, adding to the three million people already displaced within Sudan.

The new numbers underscore the urgent need for intensified humanitarian efforts and global attention to address what is now the largest displacement crisis in the world.

IOM appeals for funding for a new humanitarian response plan in Sudan

Since the crisis began, IOM has been responding to the mounting humanitarian needs in and outside Sudan, although much of its staff have been displaced themselves.

IOM is committed to addressing these urgent needs and is expanding its response with a newly launched Crisis Response Plan for Sudan, appealing for $168 million (€155 million).

The conflict in Sudan continues to have a profound impact. Critical infrastructure, including healthcare facilities, schools, roads and utilities like power and water sources, along with telecommunications assets, have been destroyed.

This devastation has drastically limited access to essentials and life-saving services. Disease outbreaks, hunger and malnutrition are an ever-present threat.

Furthermore, the chaos has heightened vulnerability to sexual and gender-based violence, putting women and girls at increased risk.
