As Palestinians have not had a fully recognized state with a regular army, much of Palestinian political violence in the context of the Israeli–Palestinian conflict has taken the form of insurgency. Common objectives of political violence by Palestinian groups include self-determination in or sovereignty over the region of Palestine, seeking a one-state solution, or the recognition of a Palestinian state. This includes the objective of ending the Israeli occupation. Goals also include the release of Palestinian prisoners held by Israel and recognition of the Palestinian right of return. Palestinian groups that have been involved in politically motivated violence include the Palestine Liberation Organization (PLO), Fatah, the Popular Front for the Liberation of Palestine (PFLP), the Popular Front for the Liberation of Palestine – General Command (PFLP-GC), the Democratic Front for the Liberation of Palestine, the Abu Nidal Organization, the Palestinian Islamic Jihad, and Hamas. Several of these groups are considered terrorist organizations by the governments of the United States, Canada, the United Kingdom, Japan, New Zealand and the European Union. Attacks have taken place both within Israel and Palestine as well as internationally. They have been directed at both military targets and civilians of many countries. Tactics have included hostage taking, plane hijacking, boat hijacking, stone throwing, improvised explosive device, knife attacks, shooting sprees, attacks with vehicles, car bombs and assassinations. In the 1990s, groups seeking to stop Israeli-Palestinian negotiations began adopting suicide bombings, predominantly targeting civilians, which later peaked during the Second Intifada. In recent decades, violence has also included rocket attacks on Israeli urban centers. The October 7 attacks resulted in massacres and hostage-taking. Suicide bombings constituted 0.5% of Palestinian attacks against Israelis in the first two years of the Second Intifada, though this percentage accounted for half of the Israelis killed in that period. As of 2022, a majority of Palestinians, 59%, believe armed attacks against Israelis inside Israel are an effective measure to end the occupation, with 56% supporting them.
