More than 10 million children in the Democratic Republic of the Congo (DRC), northeast Nigeria, the Central Sahel, South Sudan and Yemen will suffer from acute malnutrition in 2021, the United Nations Children's Fund (UNICEF) has said. All of these countries and regions are experiencing "dire humanitarian crises" while also grappling with intensifying food insecurity, the coronavirus pandemic and, with the exception of the Central Sahel, "a looming famine," UNICEF said on Wednesday.
