WikiLeaks denies exposure of U.S. State Department informants through the classified documents released by the whistleblower website.

“Totally false that any WikiLeaks sources have been exposed or will be exposed. NYT drooling, senile, and evil,” WikiLeaks tweeted.

State Department officials and human rights activists have been concerned that such diplomatic sources, including activists, journalists and academics in authoritarian countries, could face reprisals, including dismissal from their jobs, prosecution or violence

In a shift of tactics that has alarmed American officials, WikiLeaks has published on the Web nearly 134,000 leaked diplomatic cables in recent days.
