Mexican authorities have ordered the arrest of the fugitive mayor of Iguala and his wife, accusing them of ordering last month’s police attack on students from a rural teachers college. Six people were killed in the initial attacks, and 43 students have been missing for almost a month. On Wednesday, protesters set fire to Iguala’s city hall, as tens of thousands gathered in Mexico City, including fellow students from the teachers college.

Diego, student at Ayotzinapa Normal School: “Who is the most guilty person here for the extrajudicial massacre of our fallen comrades on the 26th of September and the forced disappearances of our comrades is the executive-in-chief, Enrique Peña Nieto, because he should ensure that the Mexican society is safe.”

Family members of the missing students traveled to Mexico City to attend the protest. Bernabé Abraham Gaspar’s son is among the missing.

Bernabé Abraham Gaspar, father of Adán Abraham de la Cruz: “I don’t understand what is happening with the authorities. Why do they kill students who are just starting to build their lives, to have a life and a dignified career and work?”
