France Demands Explanation From US Over NSA Claims Made By French Newspaper

Le Monde reports that the NSA spied on millions of French phone calls

French Foreign Minister Laurent Fabius has summoned the US ambassador over newspaper claims that the US spied on millions of phone calls in France.

France has labelled such activity between allies as "unacceptable".

Le Monde says the data, based on leaks from ex-intelligence analyst Edward Snowden, suggest the US NSA agency monitored businesses and officials as well as terrorism suspects.

The intercepts were apparently triggered by certain key words.
