Iran's Supreme Leader Ayatollah Ali Khamenei has ordered a direct retaliation against Israel following the assassination of Hamas leader Ismail Haniyeh in Tehran, which Iran claims was a violation of its sovereignty. Iranian envoy Amir Saeid Iravani, speaking at the UN Security Council, asserted Iran's right to self-defense under international law, labeling Haniyeh's killing as an act of terrorism. The Iranian government condemned the assassination, which took place while Haniyeh was in Iran as an official guest, and has called for international sanctions against Israel. The meeting at the UN was prompted by concerns from China and Algeria regarding the potential escalation of violence in the region. Both envoys from China and Russia criticized the assassination, emphasizing its impact on peace efforts and stability in the Middle East. Iran's leadership has indicated that it will respond appropriately to this aggression, reinforcing its stance on territorial integrity and international law.
