The NSA's interception of billions of telephone conversations, emails, Internet searches and other forms of communication made by Latin American individuals, companies and government agencies has provoked a wave of protests and demands for explanations by the Obama administration.
Snowden, the source of the secret documents, remained confined to the transit zone of Moscow's international airport Wednesday, with conflicting reports about the prospect of his finding asylum in Venezuela or elsewhere.
According to the documents reported in the Rio de Janeiro-based daily O Globo, the most intensive surveillance has been conducted against both US allies -- including Brazil, Colombia and Mexico -- and against Venezuela, whose bourgeois nationalist regime has in the past come into conflict with US aims in the region.
Also subjected to the NSA surveillance net have been Argentina, Ecuador, Panama, Costa Rica, Nicaragua, Honduras, Paraguay, Chile, Peru and El Salvador, according to the O Globo report.
The spying has involved two programs: PRISM, which collates email, Internet chats, searches and other material directly from the servers of IT companies such as Microsoft, Google, Twitter, Facebook, YouTube and Skype; and "Boundless Informant," which collects telephone calls, faxes and other communications.
