> Leaderless Palestinian youth, inspired by instructional videos and photos on social media encouraging people to "Stab a Jew," are thought to be behind a new wave of violence in Israel and the West Bank. Uncoordinated and spontaneous attacks by individual young Palestinians, mostly under the age of 25, started to occur almost daily from October 2015, with assailants often using a household weapon — a knife, axe, meat cleaver, screwdriver — before being fired upon by nearby Israeli security forces. So far, the bloodshed has claimed the lives of at least 28 Israelis and 189 Palestinians, 128 of whom Israel says were assailants.
