On 7 October 2023, the paramilitary wings of Hamas, Palestinian Islamic Jihad, PRC, PFLP and DFLP launched a series of coordinated armed incursions into the Gaza envelope of neighboring Israel, the first invasion of Israeli home territory since the Arab-Israeli War of 1948. The attacks, on a Saturday, initiated the Israel–Hamas war, almost exactly 50 years after Operation Badr and the greater Yom Kippur War of 6 October 1973. Hamas and other Palestinian armed groups named the attacks Operation Al-Aqsa Flood, while in Israel they are referred to as Black Saturday or the Simchat Torah Massacre, and internationally as the 7 October attack.
