The Spanish government has summoned the U.S. envoy in Madrid to address concerns that Washington's massive global surveillance extended to the Iberian nation, Spain's foreign minister said Friday.

Prime Minister Mariano Rajoy, currently in Brussels for a European Union summit, instructed him to call in U.S. Ambassador James Costos, Jose Manuel Garcia-Margallo told reporters after Friday's Cabinet meeting.

While insisting there is no place for espionage between "friends and allies," Rajoy said Friday his government has seen no proof that the U.S. National Security Agency targeted the communications of Spanish political leaders.

"Spain wants to have explained what has happened and to what degree the red lines have been violated. The red lines are fundamental rights: the right to personal life and to privacy," Garcia-Margallo said.

The EU, he noted, agreed in June to create a panel of experts to review the current data-protection accord with the United States in the wake of former NSA contractor Edward Snowden's initial revelations about Washington's wide-ranging espionage.

Spain also took steps on its own, Garcia-Margallo said, recalling that he sent one of his top aides to Washington in July to urge U.S. officials to find a balance between security and "respect for freedoms."

Costos will be received on Monday by Spain's secretary of state for the EU, Iñigo Mendez de Vigo, as Garcia-Margallo will be in Poland on official business, foreign ministry sources told Efe.
