The contested "Flag Parade" traditionally conduced by Jews through the Old City to celebrate Jerusalem Day will not arouse problems, Jerusalem Mayor Nir Barkat said Sunday before the march began. "Violence isn't needed to dictate reality, I think the frictions in this city always have been and always will be," he told Army Radio. Barkat told the radio station that the march has been done on the same route for years, and that "at face value, I don't think that there will be problems.""Jerusalem is celebrating, this is an appropriate march," he added. "We're talking about tens of thousands of people who take part in this day of celebration for the city."
