A Spanish newspaper has published a document it says shows the U.S. National Security Agency spied on more than 60 million phone calls in Spain in one month alone.

Spanish Prime Minister Mariano Rajoy reportedly summoned the U.S. ambassador for clarifications into the affair, The Guardian reported.

The report in El Mundo newspapers comes a week after Le Monde reported similar allegations of U.S. spying in France, and German magazine Der Spiegel reported that a document shows that Washington tapped Chancellor Angela Merkel's mobile phone.

El Mundo said that a document provided by the former NSA contractor Edward Snowden shows that the NSA monitored the phone calls from Dec. 10, 2012, until Jan. 8, 2013, but not their content.
