NSA spying row: US and Denmark pressed over allegations
European powers have pressed the US and Denmark over reports the two worked together to spy on top European politicians, including German Chancellor Angela Merkel.
Danish broadcaster DR said Denmark's Defence Intelligence Service (FE) collaborated with the US National Security Agency (NSA) to gather information from 2012 to 2014.
Mrs Merkel is among those demanding answers.
Both FE and the NSA are yet to comment.
Denmark's Defence Minister, Trine Bramsen, did not confirm or deny the report but told AFP news agency that "systemic eavesdropping of close allies is unacceptable". She was not in charge of the ministry during the alleged spying.
"This is not acceptable between allies, and even less between allies and European partners," said French President Emmanuel Macron, after speaking with Mrs Merkel.
Mrs Merkel said she agreed with Mr Macron's comments, but that she was also reassured by the Danish defence minister's condemnation.
Intelligence was allegedly collected on other officials from Germany, France, Sweden and Norway. Those nations have also called for explanations.
Norwegian Prime Minister Erna Solberg told public broadcaster NRK: "It's unacceptable if countries which have close allied co-operation feel the need to spy on one another."
