* New NSA spying revelations based on Snowden leaks
* Brazil calls in U.S. ambassador to voice "indignation"
* Mexico seeking investigation of the reported espionage
(Updates with response from Brazilian and Mexican governments)

BRASILIA, Sept 2 Brazil assailed the United
States on Monday 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 program reported on Sunday that the U.S.
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.
Brazil's government, already smarting from earlier reports
that the NSA spied on the emails and phone calls of Brazilians,
called in U.S. ambassador Thomas Shannon and gave the U.S.
government until the end of the week to provide a written
explanation of the new spying disclosures based on documents
leaked by fugitive former NSA contractor Edward Snowden.
"I expressed to (Shannon) the Brazilian government's
indignation over the facts revealed in the documents," Foreign
Minister Luiz Alberto Figueiredo said at a news conference.
"From our point of view, this is an inadmissible and
unacceptable violation of Brazilian sovereignty," he said.
Figueiredo declined to explicitly say whether the
allegations could lead Rousseff to call off her visit to
Washington, the only state visit offered by President Barack
Obama this year. The trip had been intended to highlight
improving U.S.-Brazil ties since Rousseff took office in 2011.
But, in response to a question from reporters about the
visit, he said that Brazil's response to the allegations "will
depend" on the U.S. explanation.
The report by Globo's news program "Fantastico" was based on
documents obtained from Snowden by journalist Glenn Greenwald,
who lives in Rio de Janeiro and was listed as a co-contributor
to the report.
"Fantastico" showed what it said was an NSA slide dated June
2012 displaying passages of written messages sent by Pena Nieto,
who was still a Mexican presidential candidate at that time. In
the messages, Pena Nieto discussed who he was considering naming
as his ministers once elected.
A separate slide displayed communication patterns between
Rousseff and her top advisers, "Fantastico" said, although no
specific written passages were included in the report.
Both slides were part of an NSA case study showing how data
could be "intelligently" filtered by the agency's secret
internet surveillance programs that were disclosed in a trove of
documents leaked by Snowden in June, "Fantastico" said.
STATE VISIT, F-18 JETS
The Brazilian Senate, where some members have proposed
offering Snowden political asylum in Brazil, launched an inquiry
into the secret surveillance of Brazilian Internet
communications by the NSA.
Rousseff held a Cabinet meeting on Monday that included the
country's defense, justice, communications and foreign ministers
to discuss a response to the new espionage report.
The White said it would respond to the requests of its
"partners and allies" through diplomatic channels.
"While we are not going to comment publicly on every
specific alleged intelligence activity, as a matter of policy we
have made clear that the United States gathers foreign
intelligence of the type gathered by all nations," said White
House spokeswoman Caitlin Hayden.
Mexico's Foreign Ministry said that although it could not
comment on the veracity of the report, it "categorically rejects
and condemns any kind of spying against Mexican citizens in
breach of international law."
A ministry statement added that Mexico had asked the U.S.
government for a thorough investigation of the matter and that,
if necessary, Washington should explain who was responsible.
"Mexico's foreign ministry has summoned the U.S. ambassador
to express its clear dismay and to demand that the
aforementioned investigation be carried out," it said.
In July, after initial reports of NSA surveillance of
internet communications in Latin American nations, Mexico's Pena
Nieto said it would be "totally unacceptable" if it were
revealed that the United States had spied on its neighbor and
largest business partner in the region.
The United States is hoping to sell Brazil 36 F-18 fighter
jets, but a Brazilian government official said manufacturer
Boeing's chances of landing the more than $4 billion deal have
been set back by the espionage scandal.
During a visit last month, U.S. Secretary of State John
Kerry urged Brazil not to let spying revelations derail growing
trade, diplomatic and cultural relations between the two largest
economies in the Americas. But he gave no indication the United
States would end the secret surveillance.
Kerry said the NSA surveillance was aimed at protecting
Americans and Brazilians from terrorist attacks.
Justice Minister Jose Eduardo Cardozo said on Monday the
latest revelations based on Snowden's documents show that U.S.
electronic surveillance goes beyond combating terrorism and has
political targets and may even involve commercial espionage.
Cardozo traveled to Washington last week and met with U.S.
Vice President Joseph Biden and other officials, seeking more
details on the previous, seemingly less serious set of
disclosures by Snowden regarding U.S. spying in Brazil.
