NSA tracking mobile phone locations worldwide, Snowden documents show

The National Security Agency is gathering nearly two billion records a day on the whereabouts of mobile phones around the world, according to top-secret documents and interviews with US intelligence officials, enabling the agency to track the movements of individuals — and map their relationships — in ways that would have been previously unimaginable.

The records feed a vast database that stores information about the locations of at least hundreds of millions of devices, according to the officials and the documents, which were provided by former NSA contractor Edward Snowden. New projects created to analyse that data have provided the intelligence community with what amounts to a mass surveillance tool.
