Days of student protests begin after Iranian police and hardliners attack a student dormitory at the University of Tehran.

The Iranian student protests of July 1999 (Also known as 18th of Tir and Kuye Daneshgah Disaster (Persian: فاجعه کوی دانشگاه) in Iran) (7–13 July) were, before the 2009 Iranian election protests, the most widespread and violent public protests to occur in Iran since the early years of the Iranian Revolution.

The protests began on 8 July with peaceful demonstrations in Tehran against the closure of the reformist newspaper, Salam. Following the demonstrations, a student dormitory was raided by riot police that night during which a student was killed. The raid sparked six days of demonstrations and rioting throughout the country, during which at least three other people were killed and more than 200 injured.In the aftermath of these incidents, more than seventy students disappeared. In addition to an estimated 1,200–1,400 detainees, the "whereabouts and condition" of five students named by Human Rights Watch who are believed to be detained by Iranian authorities remain unknown.
