Union and state officials say violent clashes between police and unionized teachers who are blockading roads and burning vehicles in southern Mexico have left four people dead, according to AP. The radical union is opposed to the mandatory testing of teachers as part of the government's sweeping education reform and is also protesting the arrest of union leaders on money laundering and other charges. On Sunday, an Associated Press journalist saw riot police firing on protesters in municipality of Nochixtlan in the state of Oaxaca, in an attempt to dislodge them. Isabel Garcia, a member of the union's political commission, said three people supporting the protests were killed. And a state official, who was not authorized to speak to the press and requested anonymity, said a Oaxaca state police officer was killed.
