MEXICO CITY - Mexico's governmental rights commission says 84 journalists have been killed in Mexico since 2000, and 20 more have disappeared since 2005.
The National Human Rights commission says there have been 39 attacks on journalists' offices or equipment since 2005.
Only 12 cases have resulted in convictions, meaning 91 percent have gone unpunished.
The commission said Friday that charges have been brought in 15 other cases, but the cases were apparently either dismissed or are still in trial.
The commission said the largest number of attacks have occurred in Mexico City, Veracruz, Chiapas, Mexico State and Chihuahua.
The agency called on the government to investigate the crimes, because impunity encouraged further attacks.
