Students and teachers from the Ayotzinapa Teacher Training School confronted police once again, this time trapping several of them in a tunnel just outside of the town of Tixtla in the state of Guerrero. Protesters blocked both entrances to the tunnel, at which time the police fired tear gas and supposedly non-lethal rubber bullets. Protests have been held since the forced disappearance of 43 students in late September with no acceptable response from the government. teleSUR
