In the wake of what French President Francois Hollande described as an "unacceptable" security breach, Jane Hartley was summoned to the French Foreign Ministry, according to French diplomats who spoke on condition of anonymity because they were not authorised to be publicly named.
The disclosures, which emerged yesterday in French daily newspaper Liberation and investigative website Mediapart, mean that France has joined Germany on the list of US allies targeted by the National Security Agency.
"This involves unacceptable acts that have already given rise to discussions between the United States and France," Hollande said in a statement after an emergency defense council meeting.
The statement said France has reinforced protective measures after the document release, without elaborating.

There was no instant confirmation of the accuracy of the documents, which covered intercepts from 2006-12 and WikiLeaks has a track record of publishing intelligence and diplomatic material.
An aide to Hollande's predecessor Nicolas Sarkozy told The AP that the former president considers these methods unacceptable. There was no immediate comment from former President Jacques Chirac, also targeted.
US National Security Council spokesman Ned Price released a statement yesterday saying the US is "not targeting and will not target the communications of President Hollande."
France is among several US allies that rely heavily on American spying powers when trying to prevent terrorist and other threats.
