Iran claims Israel's admission of assassinating former Hamas leader Haniyeh justifies its October missile attack, escalating diplomatic tensions after Katz's recent statements.

Hassan Nasrallah meanwhile was the leader of the Iran-backed Lebanese group Hezbollah - he was assassinated in Beirut in September as Israel dramatically escalated its military campaign against Hezbollah, with which it had been trading near daily cross-border fire since the day after the 7 October attacks.

Iravani addressed a letter to the UN, denouncing Israel's explicit admission of responsibility for the assassination of Ismail Haniyeh.
