Spain today summoned the US ambassador to discuss alleged spying on Spanish citizens, saying Washington's alleged behaviour would be "unacceptable" if true.
"Spain has relayed to the United States the importance of preserving a climate of trust ... and its interest in understanding the full reach of practices that, if true, would be considered inappropriate and unacceptable between allies," the Spanish foreign ministry said in a statement.
Madrid has also asked the United States to provide more data from the National Security Agency, it said.
The statement was issued after a meeting between Spain's Secretary of State for the European Union, Inigo Mendez de Vigo, and US Ambassador to Spain James Costos.
