Yesterday in the Mexican State of Guerrero, protests over the missing teaching students from Ayotzinapa grew violent as masked protesters wielding metal rods attacked a police vehicle. Riot police were sent to break up the protest in which 18 people were injured and a local government building torched. More forensics results came in from burned bodies found in plastic bags near a Cocula dump site. The results show the remains did not belong to any of the students. teleSUR.
