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.

The Israeli official threatened to take similar action against the leadership of the Houthi rebel group in Yemen.

The Iranian-backed Houthi rebels have escalated their missile and drone offensives against Israel throughout the war. A missile launched on Saturday struck Tel Aviv, injuring at least 16 people. In response, Israel has conducted three rounds of airstrikes in Yemen, aiming to cripple the Houthis' operational capabilities.
