The United Nations is warning rates of severe malnutrition in Ethiopia’s Tigray have risen sharply with nearly 9 million people needing food aid in the war-ravaged northern region. The World Food Programme and the U.S. government, Ethiopia’s two largest food donors, both halted deliveries to Tigray in April, saying the food was being diverted away from those in need. A Tigray official said hundreds have died, including children, since the aid was withdrawn, calling the situation “extremely desperate.”
