Spain demands US explain 'monitoring'
The US ambassador to Spain, who had been summoned by its EU minister, vowed to clear the "doubts" that had arisen about his country's alleged espionage.
The minister, Inigo Mendez de Vigo, said such practices, if true, were "inappropriate and unacceptable".
An EU delegation is to meet officials in Washington to convey their concerns.
The representatives from the European Parliament's Committee on Civil Liberties, Justice and Home Affairs are expected to speak to members of the US Congress and security officials to gather information about the recent allegations of US spying on European leaders and citizens.
