Iran is on the way to revolution:

Hundreds of Iranian hardline Islamic vigilantes, police and pro-democracy youths fought three-sided running street battles near Tehran University on Wednesday on the anniversary of 1999 student unrest.

A witness said police had fired tear gas at groups of youths near the campus and also fought fist fights with plainclothes Islamic militiamen to prevent them from engaging in further running battles with youths.

Earlier witnesses said armed Iranian Islamic vigilantes seized three student leaders as they left a news conference where they announced they had cancelled protests to mark the anniversary of 1999 university unrest.

Authorities have banned off-campus rallies, closed campus dormitories, postponed summer exams and vowed to deal strictly with any unrest after arresting 4,000 people during 10 nights of sometimes violent protests across the country in June.

There once was a time they celebrated the taking of the US embassy and the return of Ayatollah Khomeini. Now they mark the anniversary of student uprisings. Things are changing in the Gulf region.
