European intelligence agencies and not American spies were responsible for the mass collection of phone records which sparked outrage in La Belle France and Spain, the US has claimed.

General Keith Alexander, the head of the National Security Agency, said reports that the US had collected millions of Spanish and French phone records were "absolutely false".

"To be perfectly clear, this is not information that we collected on European citizens," Gen Alexander said when asked about the reports, which were based on classified documents leaked by Edward Snowden, the former NSA contractor.

Shortly before the NSA chief appeared before a Congressional committee, US officials briefed the Wall Street Journal that in fact Spain and La Belle France's own intelligence agencies had carried out the surveillance and then shared their findings with the NSA.
