Famine is now official in the Gaza Strip. The Integrated Food Security Phase Classification (IPC), an international system supported by United Nations agencies that assesses food situations worldwide, declared on Friday that famine has reached Gaza City and the other municipalities and refugee camps that make up Gaza Governorate. The IPC report comes on the eve of an offensive in which the Israeli army intends to expel the one million Gazans concentrated in Gaza City — maneuvers that humanitarian organizations have warned would have catastrophic consequences.
