Ismail Haniyeh, a prominent Hamas leader, was killed in Tehran by a bomb that was reportedly smuggled into a guesthouse two months prior to the attack. The explosive device was detonated remotely after confirming Haniyeh's presence in the building, which is protected by the Islamic Revolutionary Guard Corps. Iranian officials, along with Hamas, have blamed Israel for the assassination, although Israel has not claimed responsibility. The incident has raised fears of escalating conflict in the region, particularly between Israel and Iran or its proxies. Haniyeh's funeral took place in Tehran, attended by top Iranian officials, and his remains were later transported to Qatar for burial. The attack has prompted calls for revenge from Iranian leaders amid ongoing tensions in the Middle East.
