An Israeli policeman was charged on Wednesday with assault causing bodily harm against a 15-year-old American of Palestinian descent during a protest over the revenge killing of the teenager's cousin days before the eight week war with Gaza.

The indictment submitted to a Jerusalem court charged the policeman with grabbing the youth and throwing him to the ground, and subsequently pummelling and dragging him with help from other officers in the course of his arrest.

The U.S. State Department at the time urged a "speedy, transparent and credible investigation and full accountability for any excessive use of force" against the American teen, a video of whose arrest was circulated on the Internet.
