Documents leaked by whistleblower Edward Snowden and obtained by teleSUR reveal that the U.S. National Security Agency (NSA) extensively spied on the state-owned Venezuelan oil company (PDVSA). The spying was coordinated from within the U.S. Embassy in Caracas and involved intercepting internal PDVSA communications. It is believed that this NSA network operates in U.S. embassies throughout the world and is called the F6 group. teleSUR
