Mexican authorities say six people were killed and 53 were injured when a teachers' union protest in the southern state of Oaxaca turned violent.
Police say the demonstration against education reforms in the town of Asuncion Nochixtlan was infiltrated by armed individuals who shot at officers and threw Molotov cocktails.
The violence broke out Sunday when police attempted to remove the National Education Workers Coordinator, or CNTE, teachers who were blocking a highway.
State Governor Gabino Cue said most of those who died were young people. Two had ties to CNTE.
