A forum about the proposed changes to the Venezuelan Constitution
Thursday ended up in a fight in the Caracas Pedagogic College.
Student leader Yon Goicoechea, who was invited to the forum, was taking the floor when fellow students supporting the changes advanced by President Hugo Chávez hooted at him, preventing him from delivering his speech.
The students opposing and endorsing the reform started yelling slogans at each other. Things heated up and some students started punching each other.
An explosive device was detonated in the conference room, apparently leaving one person injured. Goicoechea was punched out of the forum.
Once outside the auditorium, the two groups clashed again verbally and physically.
