During yesterday's demonstration, the student group marched to the area of the White House, then past the State Department to the Pentagon where they protested against U.S. sales of arms to iran and shouted such slogans as "U.S. Get Out of Iran." Many of the protesters were masked.
In the late afternoon, demonstrators marched to the vicinity of the Iranian Embassy on Massachusetts Avenue NW before disbanding. There were reports of snarled traffic near Massachusetts Avenue and 34th Street, authorities, said.
