On the 6th, UN Secretary General Guterres wrote a letter to the President of the Security Council in accordance with Article 99 of the UN Charter, calling on Council members to promote the avoidance of a humanitarian disaster in Gaza. Guterres said in the letter that the international community has a responsibility to mobilize all its influence to avoid further escalation of the Israeli Palestinian conflict and end the crisis. He called on Security Council members to promote the avoidance of humanitarian disasters in Gaza and called on Israel and Palestinian armed organizations to declare a humanitarian ceasefire. Guterres' spokesperson Diarique said at a press conference that this is the first time Guterres has invoked this provision since taking office as Secretary General of the United Nations in 2017. Article 99 of the United Nations Charter stipulates that the Secretary General of the United Nations may bring to the attention of the Security Council any matter that he deems may threaten international peace and security. The United Nations Secretary General rarely cites this provision. (Lai Xin She)
