MEXICO CITY (AP) — Mexican hackers have taken over more than a dozen websites belonging to political parties and local governments and posted a message criticizing the government on the nation's Independence Day.

The hackers targeted sites such as that of the government-owned National Auditorium, the National Action Party branch in the Yucatan and the southeastern Mexican town of Macuspana.

The group calls itself Ciber Protesta Mexicana and says it's not connected to the international Anonymous hackers group.

Hacked pages displayed a black screen with text denouncing violence in Mexico, the electoral institute's certification of July 1 election results and what it says was the imposition of President-elect Enrique Pena Nieto.

The page listed the federal Congress's TV site as one of those hacked, but it was working normally Sunday afternoon.
