The US ambassador to Brazil was summoned by authorities Monday over new allegations that the US National Security Agency spied on President Dilma Rousseff, an official said.
A foreign ministry spokesman said U.S. Ambassador Thomas Shannon was called in Monday, following a report on Brazil\’s Globo TV that the United States spied on Rousseff and Mexican President Enrique Pena Nieto.
During a Sunday broadcast, U.S. journalist Glenn Greenwald, a columnist for the Guardian newspaper, said he received documents from NSA leaker Edward Snowden showing the United States intercepted the communications of the Brazilian leader, including emails and telephone calls.
Greenwald also told Globo a document dated June 2012 showed the communications of Mexican President Enrique Pena Nieto were being monitored one month before he was elected.
Rousseff is expected to travel to Washington in October for a state visit.
Former NSA contractor Snowden fled the United States in June, and then provided troves of classified material about NSA surveillance practices to U.S. and foreign media. He currently resides in Russia, which granted him temporary asylum last month.
He faces U.S. federal charges of espionage, and the theft and conversion of government property.
