Mexico teachers protest: Six killed in Oaxaca clashes Six people have been killed in southern Mexico in clashes between protesting teachers and police. More than 100 others including many police officers, were injured. The incident took place in the state of Oaxaca, where two high-profile union leaders accused of corruption were arrested last week. Members of the CNTE union, which has a history of radical activism, have been blocking roads in southern Mexico ever since the union leaders were arrested. The authorities said the police were trying to clear the roads when unknown gunmen began firing at both sides in order to create chaos and conflict. SOURCE: BBC news
