The Guardian newspaper has identified a 29-year-old former CIA technical worker as the source for leaks about US spy agencies.
The Guardian published a series of revelations that US security services monitored phone calls and internet data through large companies. Edward Snowden asked the newspaper to reveal his identity.
We hack everyone everywhere. We like to make a distinction between us and the others. But we are in almost every country in the world. We are not at war with these countries.

America's top intelligence official has called Edward Snowden's actions a "violation of sacred trust."
