Since launching its retaliatory war in Gaza, Israel claims to have eliminated the leaders of militant groups including, Sinwar, the mastermind of the 7 October attack on Israel, and Hezbollah chief Hassan Nasrallah, who was killed in an airstrike on a building complex in Beirut.

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

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.
