MEXICO CITY—Web users claiming to be in the hacking movement known as "Anonymous" say they are behind an attack on the website of a Mexican political party backing the gubernatorial race of President Felipe Calderon's sister.
The New Alliance Party's website shows a video of a person wearing a Guy Fawkes mask urging Mexicans to hack into official websites and email accounts to look for evidence of corruption and make it public.
Twitter users claiming to belong to "Anonymous" posted messages of the hack Sunday coinciding with the Michoacan state elections. They also say hacked the Michoacan Electoral Institute's website, which has been down for hours.
Presidential sister Luisa Maria Calderon is seeking the governor's seat in Michoacan's vote.
