The White House is denying recent spying allegations from a French newspaper.
A report on the French daily Le Monde claims the National Security Agency collected as many as 70.3 million phone records from French citizens in a 30-day period.
France said the behavior unacceptable and has asked the U.S. ambassador to explain why America spied on one of its closest allies.
The U.S. intelligence director issued a statement Wednesday, saying the reports "contain inaccurate and misleading information regarding U.S. foreign intelligence activities."
Meanwhile, Mexico is investigating allegations that Washington spied on its president and his predecessor.
This comes after Germany's weekly Der Spiegel published reports that the NSA hacked former Mexican President Felipe Calderon's email account.
The report says the documents describe an operation dubbed "Flat liquid" that claim to have accessed Mexico's "presidential" domain, which was also purportedly used by members of Calderon's cabinet.
Earlier documents revealed the United States had also spied on current Mexican President Enrique Peña Nieto before he was elected last year.
Mexico said it will send a diplomatic note to the United States, adding that "in a relationship of neighbors and partners, there is no room for the kind of activities that allegedly took place."
