The Iranian delegation to the UN addressed the Security Council in the wake of Defense Minister Israel Katz's remarks, which acknowledged for the first time that Israel had assassinated Hamas leader Ismail Haniyeh in Tehran, and called for punishment. "Katz publicly and shamelessly admitted that Israel was responsible for the assassination of Haniyeh, while he was visiting Tehran," according to the Iranian delegation. "This bold and shameless confession of the murder of a political leader on the sovereign territory of a UN member state once again emphasizes Israel's responsibility for its acts of terrorism and aggression. It also confirms the legitimacy of Iran's response on October 1. The UN must not allow impunity for a regime that blatantly defies international law."
