US reporter Glenn Greenwald, who published documents leaked by whistleblower Edward Snowden, is planning to reveal more information about US surveillance programmes in the coming days.
Greenwald reportedly told a Brazilian congressional hearing, which is investigating the US internet surveillance in Brazil, that more information would be pubished.
"There will certainly be many more revelations on spying by the U.S. government and how they are invading the communications of Brasil and Latin America," Greenwald said.
Greenwald claimed that Snowden gave him 15,000 to 20,000 additional secret documents.
Greenwald told Reuters that he does not believe WikiLeaks had obtained a package of documents from Snowden, and that only he and filmmaker Laura Poitras have a complete archive of the leaked material.
Snowden, who recently revealed the Prism surveillance programme of NSA, is still believed to be in Russia.
Earlier this month, Snowden revealed another secret surveillance programme, dubbed Xkeyscore, that gives the US government access to millions of people’s emails, online chats and browsing histories.
Wikileaks founder Julian Assange recently said that irrespective of the outcome regarding the situation of Snowden, his information about US surveillance programmes will continue to be released.
