Famine was officially declared Friday in part of northern Gaza, including Gaza City, by the world's leading authority on hunger as Israel vowed to destroy the area if Hamas doesn't agree to its terms.

Israel has called the United Nations' declaration of famine in parts of Gaza an "outright lie," but multiple U.N. bodies, more than 100 humanitarian groups, and several of Israel's own allies have warned for months that the war and Israel's restrictions of food into Gaza are causing starvation among civilians.
