Iran's mission to the United Nations says the Israeli defense minister's admission to the Jewish state's killing of Hamas leader Ismail Haniyeh in Tehran legitimizes Iran's October 1 attack on Israel.

"This brazen act underscores Israel’s role in terrorism, legitimizes Iran’s response on 1 October 2024, and reaffirms the Zionist regime as a serious threat to global peace, which must be stopped," the Iranian mission said in a letter to the UN Secretary General and the US Ambassador to the UN, the rotating president of the Security Council.
