America's NSA intelligence service allegedly targeted the European Union with its spying activities. According to SPIEGEL information, the US placed bugs in the EU representation in Washington and infiltrated its computer network. Cyber attacks were also perpetrated against Brussels in New York and Washington.

Information obtained by SPIEGEL shows that America's National Security Agency (NSA) not only conducted online surveillance of European citizens, but also appears to have specifically targeted buildings housing European Union institutions. The information appears in secret documents obtained by whistleblower Edward Snowden that SPIEGEL has in part seen. A "top secret" 2010 document describes how the secret service attacked the EU's diplomatic representation in Washington.

The document suggests that in addition to installing bugs in the building in downtown Washington, DC, the European Union representation's computer network was also infiltrated. In this way, the Americans were able to access discussions in EU rooms as well as emails and internal documents on computers.
