Prime Minister Mariano Rajoy says the head of Spain’s intelligence services will address Parliament over allegations that Spain was a target for surveillance by the U.S. National Security Agency.

Rajoy told a Parliament session Wednesday that Spain was taking the allegations seriously. He reiterated that if confirmed, such activity is “inappropriate and unacceptable between partners and friends.”

El Mundo newspaper Monday published a document it claimed showed the NSA tracked more than 60 million phone calls in Spain in one month alone.

The NSA said Tuesday that millions of telephone records of European citizens were swept up as part of a NATO program to protect the alliance’s members but that that the U.S. did not collect the European records alone.

Spain insists it is unaware of any U.S. spying.
