The following is a partial list of Israeli civilian casualties of the Second Intifada. The International Institute for Counter-Terrorism (IPICT) puts civilian deaths at 78% and Israeli combatants at 22%, between 27 September 2000 and 1 January 2005. According to B'tselem between the start of the Second Intifada and Operation Cast Lead, 731 Israeli civilians and 332 members of the Israeli security services have been killed. The Israeli civilians' deaths do not show a high regularity in their age or gender distribution, as Palestinian militants chose to attack whichever civilian targets were accessible. The targets included the Dolphinarium disco attack, a place frequented by Israeli youth, and open-air markets and public buses, which are disproportionately used by women and the elderly. A number of attacks against Israeli civilians have been considered massacres.
