MOSCOW, December 11 (RAPSI) – The Supreme Court of Germany has yet to uncover any tangible evidence supporting the claim that Chancellor Angela Merkel phone was tapped by American intelligence services, according to Attorney General of Harald Range.

At a press conference on Thursday, Range said that German authorities had no official NSA documents on ordering any surveillance. NSA refused to make any comment on the situation.

According to the documents leaked by NSA whistleblower Edward Snowden, given to the German magazine Spiegel in the summer of 2013,  the NSA monitored the telephone conversations of Chancellor Angela Merkel and other members of the German political and economic elite.

According to the leaks, NSA had carried out surveillance on chancellor Angela Merkel’s mobile phone for more than 10 years, and that her cell phone number had been on a special list of an NSA unit known as the Special Collection Service (SCS), since 2002.

In May members of the German parliamentary commission, which is investigating the US National Security Agency’s questionable activity, wanted the heads of US high-tech companies, including Apple, Facebook, Twitter and Google, to testify to the Bundestag.
