On 31 July 2024, Ismail Haniyeh, the political leader of Hamas, was assassinated along with his personal bodyguard in the Iranian capital Tehran by an apparent Israeli attack.[5] Haniyeh was killed in his accommodation in a military-run guesthouse after attending the inauguration ceremony for Iranian president Masoud Pezeshkian.[6]Nasser Kanaani, the spokesman of the Ministry of Foreign Affairs of Iran, condemned this assassination and said that Haniyeh's "blood will never be wasted".[7]
The cause of Haniyeh's death is under investigation by Iran's Islamic Revolutionary Guard Corps (IRGC).[8] Differing reports emerged as to how he was killed, ranging from a missile strike[5] to a remotely detonated explosive device previously hidden in his bedroom at the IRGC-run guesthouse.[9] According to analysts, the assassination exposed critical security flaws.[10][11] The investigation has led to the arrest of over two dozen individuals, including senior intelligence and military officials, as well as staff from the guesthouse.[10]
