UNITED NATIONS (AP) — The head of the U.N. food agency is warning that 16 million people in Yemen “are marching towards starvation” and says food rations for millions in the war-torn nation will be cut in October unless new funding arrives. At a virtual pledging conference co-hosted by Sweden and Switzerland on March 1, U.N. Secretary-General Antonio Guterres appealed for $3.85 billion for Yemen this year. In major pledges, U.S. Secretary of State Antony Blinken announced an additional $290 million in humanitarian assistance for Yemen and the European Union said it was allocating an additional 119 million euros (about $139 million) in humanitarian and development aid. A Saudi-led coalition entered the war in March 2015, backed by the United States, to try restore Hadi to power, and threw its support behind his internationally backed government. Despite a relentless air campaign and ground fighting, the war has deteriorated largely into a stalemate and spawned the world’s worst humanitarian crisis.
