United Nations (UN) Secretary-General António Guterres on Wednesday invoked Article 99 of the UN charter for the first time, citing a “severe risk of collapse of the humanitarian system in Gaza,” as the war rages on between Israel and militant group Hamas. In a letter to José Javier De la Gasca Lopez Domínguez, the current UN Security Council President, Gutteres said he expects “public order to completely break down due to desperate conditions, rendering even limited humanitarian assistance impossible.”
