UN chief Antonio Guterres urged leaders not to use hunger as a weapon of war, as 280 million Africans face chronic hunger amid conflict, climate change, and aid cuts. Speaking at the UN Food Systems Summit in Ethiopia, he warned of worsening crises in Africa, Gaza, and Sudan. The African Union called for more global support, noting millions are on the brink of famine. A UN report showed global hunger slightly declined in 2024, but 720 million still face hunger, with Africa hardest hit.
