Mexican government meets with radical teachers' union

Protesting teachers, accompanied by a mediation commission, huddle together in discussion inside the courtyard of the Interior Ministry, as they await the start of a meeting with Secretary of the Interior Miguel Angel Osorio Chong, in Mexico City, Wednesday, June 22, 2016. The negotiations between the striking radical teachers and the government come three days after a clash between protestors and police in Oaxaca state left eight dead. Though who started shooting is disputed, journalists filmed police firing their weapons in the confrontation, which also left more than 100 injured.
