The Brazilian government called for international regulations to protect the privacy of citizens and governments on Monday following allegations that the US National Security Agency (NSA) spied on Brazilian President Dilma Rousseff.

According to The Washington Post, a report citing 2012 NSA documents leaked by Edward Snowden, showing that the US had intercepted Rousseff’s calls and emails, aired Sunday night on Globo TV. There have been allegations that the NSA spied on Mexican President Enrique Pena Nieto as well.

Speaking on the subject, Brazilian Foreign Minister Luiz Alberto Figueiredo said, “We’re going to talk with our partners, including developed and developing nations, to evaluate how they protect themselves and to see what joint measures could be taken in the face of this grave situation.”

Figueiredo sought a written explanation from US ambassador Thomas Shannon which will arrive later this week, The Wall Street Journal reports. For now, a State Department official has stated that the US government will respond with diplomacy and will not comment "on every specific alleged intelligence activity."
