Amnesty International is calling on the Mexican government to investigate a slew of human rights abuses in the state crackdown on the popular uprising in Oaxaca. Striking teachers have led a more than year-long campaign against the state governor, Ulises Ruiz. Amnesty says it’s found many cases of state-sanctioned torture of imprisoned protesters. Activists have also accused state police of more than a dozen extrajudicial killings. Speaking from Mexico City, Amnesty International Director Irene Khan called for a probe into Ruiz’s government. After meeting with Khan, Ruiz dismissed Amnesty’s findings and said the group had collaborated with his opponents in the Popular Assembly of the Peoples of Oaxaca, or APPO.

Oaxaca Governor Ulises Ruiz : “We do not share views with Amnesty International’s report, and we let them know. Those who write the report for Amnesty International are councilors for the APPO.”

Amnesty’s Irene Khan had this response.

Amnesty International Director Irene Khan: “The report was not written by APPO. Amnesty International’s reports are written by Amnesty International’s own researchers, and for the governor to make an allegation like that is totally irresponsible. He has no evidence to show, to prove that. He does not take our recommendation seriously, and he is simply finding an excuse not take our recommendations.”
