BRASILIA, July 4 -- The United States spied on the communications of dozens of senior Brazilian officials other than President Dilma Rousseff, local media reported on Saturday.

Wikileaks published 29 phone numbers monitored by the U.S. National Security Agency (NSA), including some Brazilian ministers, diplomats, and "important figures".

The relations between Brazil and the U.S. turned tense in 2013 when former NSA contractor Edward Snowden revealed that the U.S. had spied on the Brazilian president. Rousseff canceled her state visit to the U.S. in late 2013.

Rousseff visited the U.S. in late June, saying "some things have changed" since the spying revelations due to assurances from Obama and the U.S. government that they would no longer engage in intrusive acts of spying on friendly countries.

Obama said that Rousseff's visit to the U.S. "marks one more step in a new, more ambitious chapter" in the relations between the two countries.

Wikileaks reportedly has also revealed, during the last two weeks, new information on U.S. spying on some senior German government officials, former and current French presidents and leading financial figures.
