TEH04:IRAN:TEHRAN,12JUL99 – A student at Tehran university holds up a T-shirt belonging to a friend who was beaten up by hardline vigilantes during a protest July 12. Fresh violence erupted in Iran on Monday as club-wielding police clashed with several hundred protesting students in a Tehran square, witnesses said. Police dispersed the students because they did not have a permit to hold a public protest. fms/Photo by Jamshid REUTERS
