The United Nations World Food Programme warned that food insecurity in Gaza has reached critical levels, with one in three residents going without any food for several days at a time. The agency said the figure underscores a deepening humanitarian crisis in the enclave, where access constraints and funding shortfalls continue to block regular deliveries of aid. The warning came as the broader UN system carried out emergency airdrops of food into remote parts of South Sudan, highlighting the scale of parallel hunger emergencies that the organisation is confronting worldwide.
