On October 7, 2023, Hamas launched a surprise attack on Israel, launching approximately 2,200 rockets in the initial barrages, making it the largest rocket attack against Israel since Hamas took control of Gaza in 2007. The number of rockets was an order of magnitude larger than previous attacks during the 2014 and 2021 crises. Iran appears to have been involved in planning the attack, with Iranian security officials reportedly helping plan the assault at a meeting in Beirut. This question will resolve as **Yes** if, after October 9, 2023, and before January 1, 2024, credible sources report that Israel has carried out an attack on Iran with damage occurring within its borders, killing at least five Iranians, and that Israel either explicitly acknowledged and taken credit for the attack or performed it in an unobscured manner.
