MEXICO CITY (AP) -- Mexico's Chamber of Deputies has filed a complaint with federal prosecutors after teachers tried to break into a legislative session during a march against Mexico's education reform, according to a Tuesday statement by the lower house of Congress.
Television video showed about 500 teachers clashing with police in riot gear late Monday in the parking area of Congress after teachers tried to get inside the complex.
The protesters did not reach the chamber where the lower chamber's Education Committee voted to approve regulations implementing a constitutional education reform signed into law earlier this year. But demonstrators broke windows and set cars afire.
Federal police, congressional security forces and teachers were injured in the clash, and the melee was quelled when federal police forced teachers back out to the sidewalks, the statement said. It added that a formal complaint had been filed with federal prosecutors to investigate and find those responsible.
The chamber also called on teachers to change their tactics and to focus on dialogue.
The most controversial piece of the reform would create a professional system for hiring, evaluating and promoting teachers without the "discretionary criteria" currently used in a system where teaching positions are often bought or inherited.
