The motivations of the recent attackers have varied. Three of the attackers have been Arab citizens of Israel who were believed to support the Islamic State, the extremist group that is not part of the Palestinian nationalist movement. The shooter in Bnei Brak was a Palestinian from the occupied West Bank who had previously served 30 months in an Israeli jail for conspiracy to commit manslaughter and for throwing objects at vehicles.
No Palestinian militant group claimed responsibility for any of the attacks, but some groups, including Hamas, the Islamist militant group based in the Gaza Strip, praised them and said that they were a natural response to the Israeli occupation. Israel has occupied the West Bank since 1967 and, with Egypt, has maintained a blockade of the Gaza Strip since 2007.
While the Palestinian Authority manages about 40 percent of the West Bank, the Israeli Army still conducts daily raids even in areas run by the authority, and Israel operates a two-tier justice system in the territory — one for Israeli settlers and one for Palestinians.
Mr. Kirschenbaum, the medic, said he took heart from the presence of both Arab and Jewish emergency responders at the scene. “We’re all working together against terror, to save lives,” he said.
