The first stage of the Intifada began following an incident at the Erez checkpoint where four Palestinian residents of the Jabalya refugee camp were killed in a traffic accident involving an Israeli driver. Rumors spread that the deaths were a deliberate act of revenge for an Israeli shopper who was stabbed to death by a Palestinian in Gaza four days earlier. Mass rioting broke out, and within weeks, partly upon consistent requests by Abu Jihad, Arafat attempted to direct the uprising, which lasted until 1992–93. Abu Jihad had previously been assigned the responsibility of the Palestinian territories within the PLO command and, according to biographer Said Aburish, had "impressive knowledge of local conditions" in the Israeli-occupied territories. On 16 April 1988, as the Intifada was raging, Abu Jihad was assassinated in his Tunis household by an Israeli hit squad. Arafat had considered Abu Jihad as a PLO counterweight to local Palestinian leadership in the territories, and led a funeral procession for him in Damascus.
