Snowden Spying Claims: US 'Bugged EU Offices' European Union offices in Brussels and the US were bugged by Washington, according to fresh spying allegations reportedly made by fugitive Edward Snowden. The German weekly news magazine Der Spiegel reported the new claims by the former US intelligence analyst, who is on the run from US authorities seeking his extradition over intelligence leaks. It said its report was based on confidential documents, some of which it had been able to consult via Snowden. One document describes how the US National Security Agency (NSA) installed microphones in a building housing the EU's diplomatic mission in Washington.

The EU delegation at the UN was also subject to similar surveillance and leaked documents referred to the Europeans as "targets," according to the report. And the spying also extended to the 27-member bloc's Brussels headquarters. Der Spiegel referred to an incident "more than five years ago" when EU security experts discovered telephone and online bugging devices at the Justus Lipsius building. In 2003, the EU announced it had found phone taps in the building targeting the offices of several countries, including Britain, France and Germany. EU Parliament President Martin Schulz It was not immediately clear if Der Spiegel was referring to this case. The latest claims are likely to strain America's relations with its European partners. European Parliament President Martin Schulz has demanded a full and speedy clarification from Washington. He said: "I am deeply worried and shocked about the allegations of US authorities spying on EU offices. If the allegations prove to be true, it would be an extremely serious matter which will have a severe impact on EU-US relations. US spying was "out of control," said Luxembourg Foreign Minister Jean Asselborn. "The US would do better to monitor its intelligence services instead of its allies," he added. Even before the latest allegations, the EU's Justice Commissioner Viviane Reding wrote to US Attorney General Eric Holder earlier this month calling for answers about its internet spy programme. In a speech on June 14, he said: "Fundamentally, this is a question of trust. Trust of citizens towards their governments and to the governments of partner nations. Earlier this month, Snowden revealed details of the top-secret Prism programme operated by the NSA. EU Commission at the EU headquarters in Brussels He subsequently fled to Hong Kong before escaping to Moscow where he is currently in transit in an airport awaiting asylum from a country that will accept him. Prism collects and analyses information from internet and phone users around the world, with access to data from Google, Yahoo! and other internet firms. US officials say the information gathered is vital in the fight against global terrorism. Meanwhile, the diplomatic squabbling over the fate of Snowden continues. Ecuador's President Rafael Correa said that US Vice President Joe Biden had, in a telephone conversation on Saturday, asked him to reject any asylum request from Snowden. But in a television interview later, Mr Correa said Snowden's fate was in Russia's hands as Quito could not process his asylum until he was on Ecuadoran soil. The president said his government would listen to opinions from US authorities, but that the final decision rested with Ecuador. "We have not sought out this situation," said Mr Correa. "Snowden is in contact with (WikiLeaks founder Julian) Assange, who recommended he seek asylum in Ecuador," he added. Ecuador has already granted refuge to Australian activist Assange, founder of the anti-secrecy WikiLeaks website. Assange, who is wanted for questioning in Sweden on sex assault allegations, took refuge at the Ecuadoran embassy in London a year ago to avoid Britain putting him on a plane to Stockholm.
