From Al-Jazeera:
Argentine teachers have held a one-day nationwide strike after a high school chemistry teacher was killed by police last week during a protest over pay in the southern province of Neuquen.
In Buenos Aires, the capital, workers at banks, hospitals, government offices, and public transportation joined the strike for an hour on Monday afternoon.
Police in the northern city of Salta fired tear gas at groups of protesters, local media said.
Carlos Fuentealba, a 41-year-old teacher, died on Thursday, a day after he was hit in the head by a tear gas cartridge when police broke up a teachers’ protest and road block in Neuquen.
