Scores of Israeli settlers went on a violent rampage in the northern West Bank late Sunday, setting dozens of cars and homes on fire after two settlers were killed by a Palestinian gunman. The deadly shooting, followed by the late-night rampage, immediately raised doubts about Jordan’s declaration that Israeli and Palestinian officials had pledged to calm a year-long wave of violence. Photos and video on social media showed large fires burning throughout the town of Hawara — scene of the deadly shooting earlier in the day — and lighting up the sky.
