The activist hacker group Anonymous attacked three Mexican government websites on Friday in protest at a proposed bill that seeks to toughen local laws about online file-sharing.

The affected sites belong to the Interior Ministry, the Senate and the Chamber of Deputies. The homepage of the Interior Ministry remained offline by mid-afternoon.

We demand the Mexican government not continue with this law because they will take away our freedom of speech and file sharing, Anonymous said in a video posted on Youtube ahead of Friday's action.
