The so-called "German NSA dossier" leaked on the Internet. According to Edward Snowden, over 50 files in the dossier contain information about the locations, where NSA agents stay in Germany.
Also, the documents show that U.S. special services did not only exchange information with Berlin, but also organized training courses for German colleagues. Among European countries, the NSA is said to conduct most active work in Germany.
In July 2013, CIA officer Edward Snowden passed secret information to the press,. It turned out that the NSA spies not only on American, but also foreign citizens, including top European officials, such as German Chancellor Angela Merkel. Snowden left the United States, where he faces either up to 30 years in prison or death penalty, and went to Latin America. However, due to the fact that the U.S. revoked his passport, he had to stay in Russia.
