Security forces fire tear gas at demonstrating students

On 7 December 2008 members of the State Security Forces (SSF) reportedly fired tear gas into a large crowd of students at Boali Sina University in Hamedan, who were demonstrating on the anniversary of Student Day. Security forces attempted unsuccessfully to force students from a university building. The SSF was dispatched to several other universities to stop students from gathering. At Tehran University, student protesters demanded that Iranian President Mahmoud Ahmadinejad release three students who have been detained since May.
