London, October 25 (RHC)-- A new document by U.S. whistleblower Edward Snowden reveals that Washington has monitored the telephone conversations of 35 world leaders. The London-based newspaper The Guardian reported that officials from the White House, the U.S. Department of Defense, and the State Department gave the world leaders’ numbers to the National Security Agency.

One unnamed U.S. official handed over 200 numbers, including those of the 35 world leaders, none of whom is named, according to the document. The once confidential memo said: "A U.S. official provided NSA with 200 phone numbers to 35 world leaders. Despite the fact that the majority is probably available via open source, the PCs [intelligence production centers] have noted 43 previously unknown phone numbers."

The new revelation came just one day after German Chancellor Angela Merkel announced that Washington is tapping her mobile phone. Merkel said: "We need trust, and now the trust has to be re-established. Spying among friends is never acceptable.”

During a press conference on Thursday, White House spokesman Jay Carney acknowledged Washington is suffering from the NSA revelations. Carney said that the revelations "have clearly caused tension in our relationships with some countries, and we are dealing with that through diplomatic channels.”

The documents released over the past few months reveal a troubling picture of a super spy agency that has sought and won far-reaching surveillance powers to run complex domestic data collection without anyone having full technical understanding of the process.

The privacy violations were first revealed by Snowden in June. He leaked confidential information that showed the NSA collects data of phone records and Internet communication of American citizens.

The former NSA contractor, who is charged with espionage in the United States, fled the U.S. and took one-year asylum from Russia in August. Snowden supplied reporters with 50,000 secret documents.
