President Dilma Rousseff told the General Assembly the eavesdropping amounted to "grave violations of human rights" and urged the U.N. to adopt a set of international norms that would guarantee Internet privacy.
"We are ... confronting a case of grave violations of human rights and civil liberties as well as the invasion and capture of secret information about the activities of companies and above all, disrespect for the national sovereignty of my country," Rousseff said in her address.
"This is the moment for us to create the conditions to avoid cyberspace becoming used as a weapon of war, through espionage and sabotage and attacks against the systems and infrastructure of other countries," she added.
The Financial Times noted Rousseff last week canceled plans for an official visit to the United States in protest over the alleged spying. She also has called for new regulations on the Internet in Brazil, such as storing all data on Brazilian citizens within Brazil's borders.
