On 31 July Hamas political leader Ismail Haniyeh, along with his bodyguard, was killed in an airstrike in Iran, an act labelled a ‘severe escalation’ by the Palestinian terror group. His death came hours after he attended a swearing-in ceremony for new president Masoud Pezeshkian. Pezeshkian vowed to defend Iran's integrity and retaliate against the perpetrators. This assassination, attributed to Israel, follows the killing of Hezbollah’s top military leader in Beirut; Israel claimed that he was responsible for a rocket attack on 27 July which killed twelve people, mainly children. Haniyeh, based in Qatar and the face of Hamas’ international diplomacy, was the highest-ranking official killed since the conflict began; his three sons have also been killed.
