Famine is reported to be spreading in Sudan amid relentless war between the military and a notorious paramilitary group that devastated the country and created the world’s largest displacement crisis.

The Sudanese government has suspended its participation in the global hunger-monitoring system on the eve of a report that’s expected to show famine spreading across the country, a step likely to undercut efforts to address one of the world’s largest hunger crises.

The world’s leading experts on hunger, the Integrated Food Security Phase Classification (IPC) Famine Review Committee, found that famine has spread in Sudan.

Famine is rapidly spreading in Sudan due to ongoing conflict between the military and a paramilitary group, creating a dire humanitarian crisis. The Integrated Food Security Phase Classification has identified famine in multiple regions.

Famine in Sudan has expanded to five areas and will likely spread to another five by May, the global hunger monitor reported Tuesday, while warring parties continue to disrupt humanitarian aid needed to alleviate one of the worst starvation crises in modern times.
