Britain's equivalent to the U.S. National Security Agency, the Government Communications Headquarters, has tapped into many of the world's key international fiber optic cables and is routinely downloading and analyzing vast quantities of Internet and phone traffic, sharing the data with the NSA. The Guardian newspaper posts classified documents showing intelligence analysts have broad access to intercepted communications but aren't supposed to "target" Americans. The National Security Agency can keep copies of intercepted communications from or about U.S. citizens if the material contains significant intelligence or evidence of crimes. That's according to exemptions in NSA's top secret rules published Thursday in the latest leak of classified U.S. materials.
