Glenn Greenwald, the US journalist who published documents leaked by fugitive former US intelligence contractor Edward Snowden, plans to make new revelations "within the next 10 days or so" on secret US surveillance of the Internet.

"The articles we have published so far are a very small part of the revelations that ought to be published," Greenwald said at a Brazilian congressional hearing on Tuesday that is investigating US Internet surveillance in Brazil.

"There will certainly be many more revelations on spying by the US government and how it is invading the communications of Brazil and Latin America," he said in Portuguese.

The Rio de Janeiro-based columnist for British newspaper The Guardian said he has recruited the help of experts to understand some of the 15,000 to 20,000 classified documents from the US National Security Agency that Snowden gave him, some of which are "very long and complex and take time to read".
