Spain summoned the US ambassador on Monday to discuss allegations of spying on Spanish citizens that it said could break the climate of trust between the two countries if proved true. Earlier, the Spanish newspaper El Mundo said the NSA had recently tracked over 60 million calls in Spain in the space of a month, citing a document which it said formed part of papers obtained from ex-NSA contractor Edward Snowden. ‘I had been in touch with (the US ambassador) before this morning’s meeting...So far, we have no official indication that our country has been spied on,’ Spanish Foreign Minister Jose Manuel Garcia-Margallo said at a joint news conference with his Polish counterpart in Warsaw. ‘As in previous occasions, we’ve asked the US ambassador to give the government all the necessary information on an issue which, if it was to be confirmed, could break the climate of trust that has traditionally been the one between our two countries.’ Madrid has also asked the United States to provide more data from the National Security Agency (NSA), the foreign ministry said.
