BERLIN: Washington targeted European Union (EU) offices in Brussels and the United States (US), German weekly Der Spiegel reported on Sunday, in fresh spying allegations attributed to US fugitive Edward Snowden.
The story, the latest in a series of allegations about US intelligence activity, is likely to further strain relations with its European partners.
European Parliament President Martin Schulz said in a statement that he was shocked at the allegations and demanded full clarification from Washington.
Der Spiegel said its report was based on confidential documents, some of which it had been able to consult via Snowden.
It was former intelligence analyst Snowden who earlier this month revealed details of the so-called Prism program operated by the US National Security Agency (NSA).
He is currently in the transit area at Moscow airport, seeking a country that will accept his request for asylum.
One document, dated September 2010 and classed as “strictly confidential,” describes how the NSA kept tabs on the European Union’s diplomatic mission in Washington, Der Spiegel said.
Microphones were installed in the building and the computer network infiltrated, giving the agency access to e-mails and internal documents.
The EU delegation at the United Nations was subject to similar surveillance, Der Spiegel said: the leaked documents referred to the Europeans as “targets.”
And the spying also extended to the 27-member bloc’s Brussels headquarters.
