Brazil, Mexico ask US to explain if NSA spied on presidents

BRASILIA (Reuters) – Brazil assailed the United States yesterday after new allegations that Washington spied on President Dilma Rousseff, complaining that its sovereignty may have been violated and suggesting that it could call off Rousseff’s planned state visit to the White House next month.
A Brazilian news programme reported on Sunday that the US National Security Agency spied on emails, phone calls and text messages of Rousseff and Mexican President Enrique Pena Nieto, a disclosure that could strain Washington’s relations with Latin America’s two biggest nations.
Mexico asked the United States to investigate the allegations, saying they would be a serious violation of its sovereignty if proven true.
