Brazil has announced a probe of U.S. spying efforts inside its borders. A report based on documents provided by Edward Snowden says the National Security Agency has tapped into Brazil’s telecommunication network and indiscriminately intercepted, collected and stored the email and telephone records of millions of Brazilians for years. The Brazilian government will look into whether local firms cooperated with the United States. Brazilian President Dilma Rousseff said if confirmed, the NSA operation would be a violation of national sovereignty.

Brazilian President Dilma Rousseff: “It is definitely a violation of sovereignty, without a doubt, just as it is a violation of human rights. Now we have to see, without rashness or prejudgment. We have to investigate. Brazil’s position is very clear and very strong: We do not agree in any way with these kinds of interferences, not just in Brazil, but in any country.”

Rousseff says her government will also raise the spying issue at the United Nations in the hopes of securing new international protections for privacy rights.
