An estimated 756,000 people in Sudan could face catastrophic food shortages by September, according to a preliminary projection United Nations agencies and aid groups use to determine whether to officially declare a famine.

The preliminary results, as of June 1 and seen by Reuters, reflect a rapidly deteriorating situation in the war-torn country.

The most recent previous projection, released in December, showed that 17.7 million people, or 37% of the population, faced high levels of food insecurity, but none were considered in a catastrophic situation.
