Story highlights WikiLeaks says the U.S. spied on officials in Brazil, not just its President

Brazilian official says information is "very similar" to that of the Snowden leak in 2013

Brazil's President said she has assurances from President Obama that spying has stopped

(CNN) WikiLeaks released a list of 29 Brazilian phone numbers of government and finance officials it says were "selected for intensive interception" by the U.S. National Security Agency. The group said the release shows that spying by the U.S. in the South American nation went further than eavesdropping on its President.

But there was no indication in the list that the spying took place more recently than 2013, and Brazilian officials brushed it aside as old news.

"The revelations of today are very similar to the ones that were released earlier," Brazil's minister of public affairs told CNN, referring to information leaked by security contractor Edward Snowden in 2013 that revealed American authorities had been spying on Brazil's President Dilma Rousseff's cell phone and e-mail communications, as well as those of many of her advisers and oil giant Petrobras.

On Tuesday, Rousseff said things had changed and she had assurances from President Barack Obama and the U.S. government that intrusive spying on friendly countries had stopped.
