Re'im music festival massacre

On 7 October 2023, the Palestinian Islamist militant group Hamas initiated a surprise attack on Israel from the Gaza Strip. As part of the attack, 364 civilians were killed and many more wounded by Hamas at the Supernova Sukkot Gathering, an open-air music festival during the Jewish holiday of Shemini Atzeret near kibbutz Re'im. At least 40 hostages were also taken. This mass killing had the largest number of casualties out of a number of massacres targeting Israeli civilians in villages adjacent to the Gaza Strip, that occurred as part of the 7 October attack, alongside those at the moshavim of Netiv HaAsara, Be'eri, Kfar Aza, Nir Oz and Holit.
