International observers removed computer equipment and personal belongings from their offices on Saturday, days after violent protests against cartoons depicting the prophet Muhammad forced them to abandon this volatile West Bank City. Gunhild Forselv, a spokeswoman for the observers, said workers were taking "essential" equipment, such as hard disks, needed for the office to continue work from its temporary base in Tel Aviv. Some workers also took personal belongings left behind during Wednesday's hasty retreat. "We're not packing up for good," she said, adding that the observers plan to return to Hebron as soon as the security situation permits. The unarmed European observers fled Hebron after crowds overpowered Palestinian police guarding the headquarters, smashed windows and threw stones at building. It was the most violent Palestinian against the cartoons, which have sparked violent unrest throughout the Muslim world.
