PARIS — WikiLeaks published documents late Tuesday that it says shows the United States National Security Agency eavesdropped on the last three French presidents.

There was no immediate confirmation of the accuracy of the documents released in collaboration with Libération, a left-leaning French newspaper, and the investigative website Mediapart.

A WikiLeaks spokesman, Kristinn Hrafnsson, told The Associated Press he was confident the documents were authentic, saying that WikiLeaks’ previous mass disclosures have proved to be accurate.

Claudine Ripert-Landler, a senior spokeswoman for President François Hollande of France, said on Tuesday night that Mr. Hollande would convene “the Defense Council to evaluate the nature of the information reported in the media and draw the necessary conclusions.” The council, which is similar to the United States National Security Council, was expected to meet Wednesday morning. There was no immediate comment from the White House or from former President Jacques Chirac.
