Palestinians fired at an Israeli military jeep along the Gaza border on Friday, hitting the vehicle but causing no injuries, and three Palestinian protesters were wounded by Israeli fire during disturbances along the border fence, the Israeli military said. The confrontations erupted three days after Gaza militants fired a rocket into Israel for the first time since a cease-fire agreement took hold in November. In addition, hundreds of Palestinians held rallies in several locations across the West Bank to protest the death of a Palestinian prisoner in an Israeli jail last weekend. The prime minister of the Palestinian Authority, Salam Fayyad, was hustled away from a protest in Bilin after he inhaled tear gas fired by Israeli soldiers, and two Palestinians were injured elsewhere, according to Palestinian reports. The military said that it had used tear gas and rubber bullets to disperse rioters and that one soldier had been injured by a rock.
