Teachers in Argentina are going on strike today to protest the fatal shooting of a teacher by police during a protest last week. Carlos Fuentealba, who taught chemistry, died after being hit by a tear gas canister fired at close range by police. He was taking part in a teacher-led march in the city of Neuquen calling for better wages. Protests have been intensifying in Argentina for days. Protesters have now blocked the main roads to Neuquen, cutting off the provincial capital from the rest of the country.
