Spain has urged the United States to give details of any eavesdropping, amid reports that it monitored 60 million Spanish telephone calls in a month. The US ambassador to Spain, who had been summoned by its European Union 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.
