Clashes broke out in Chile's capital on Thursday between protesters and police as students continued their demands for education reform.
The march in Santiago was the latest demonstration in a movement begun May of 2011 calling for free, quality schooling for all and denouncing the privatization of education.
"Excessive amounts of tear gas and water cannons were used. There were too many police here today," humans rights observer Elisa Disqueto told The Santiago Times.
Javiera Campos Menendez, another human rights observer, agreed, telling the Santiago Times, "(There was) very little respect for human rights today. We have just witnessed three completely illegal arrests of protesters for no motive," she said.
