Sudan again topped the International Rescue Committee’s watchlist of global humanitarian crises as warring sides continued a conflict that has killed tens of thousands of people.

It is the third time in a row that Sudan has headed the list, which was published Tuesday. It highlights the 20 countries most at risk of new or worsened humanitarian emergencies.

"What the IRC is seeing on the ground is not a tragic accident. The world is not simply failing to respond to crisis; actions and words are producing, prolonging, and rewarding it," IRC CEO David Miliband said in a statement.

"The scale of the crisis in Sudan, ranking first on this year’s Watchlist for the third year in a row and now the largest humanitarian crisis ever recorded, is a signature of this disorder," he added.

War erupted in April 2023 from a power struggle between the Sudanese army and the paramilitary Rapid Support Forces ahead of a planned transition to civilian rule, and triggered the world's largest displacement crisis.
