German news Magazine Der Spiegel broke the news earlier today that NSA-sanctioned bugs were installed in the EU building in downtown Washington, DC. The report indicates that the EU’s internal computer network was also infiltrated, with the NSA gaining access to internal emails and documents.

Furthermore, the Der Spiegel report has uncovered evidence linking the NSA to an undercover, eavesdropping operation in Brussels nearly 5 years ago. EU security officers noticed strange calls targeting the European Council, which were ultimately traced back to a NATO-compound NSA office.

Reuters has reported that Martin Schulz, the president of the European Parliament, has expressed severe concerns about US-EU relationships if the report’s findings are confirmed. In an e-mail statement, Martin Schulz said:

“On behalf of the European Parliament, I demand full clarification and require further information speedily from the U.S. authorities with regard to these allegations”

An official spokesman for the Office of the U.S Director of National Intelligence has yet to offer a comment or official statement on the Der Spiegel report or Martin Schulz’s comments.
