The Israeli military clamped curfews Saturday on dozens of towns and refugee camps in the occupied territories in a bid to prevent violence on the eve of the anniversary of the assassination of the deputy PLO chief.

The April 16, 1988, assassination of Khalil Al-Wazir, widely known among Palestinians as Abu Jihad, sparked the bloodiest day of rioting in the Palestinian uprising in the West Bank and Gaza Strip. Israeli soldiers killed 14 Arabs in the violence.
