Brazil has condemned a U.S. spy program that reportedly targeted President Dilma Rousseff, labeling it an "unacceptable invasion" of its sovereignty.
A Brazilian news program reported on September 1 that the U.S. National Security Agency spied on e-mails, phone calls, and text messages of Rousseff, as well as Mexican President Enrique Pena Nieto.
The report citied documents leaked by the fugitive former U.S. intelligence contractor Edward Snowden.
The Foreign Ministry on September 2 called in U.S. Ambassador Thomas Shannon and told him Brazil expected the White House to provide a prompt written explanation over the espionage allegations.
Mexico also asked the United States to investigate the allegations, saying they would be a serious violation of its sovereignty if proven true.
