[3] Other examples included the destruction caused by public works to the historic city center of the state capital.

Some intellectuals called the destruction so appalling that they feared that UNESCO would retire the city's declaration as a World Heritage Site.

While initially not involved in the conflict, the Federal government has since sent a commission to help in the negotiations and has called for the governor to step down.

Armed groups have fired on popular protests,[12] and on August 21 and 22 attacked radio stations held by the APPO.

[13] At least seventeen people have been killed in Oaxaca, almost of them by police or paramilitary forces allied with Ulises Ruiz Ortiz since the onset of the conflict, including US IndyMedia Journalist Bradley Roland Will.

[15] On November 6, 2006, the conflict escalated after five groups committed a series of small bombing attacks in Mexico City demanding Ruiz's resignation.

[18] Ulises Ruiz handed over the governorship of Oaxaca to Gabino Cué Monteagudo of the opposition Convergencia party on 1 December 2010.

[22] In September 2023, he filed paperwork with the National Electoral Institute enabling him to collect signatures for a possible run as an independent candidate for President of Mexico in the 2024 general election.
