Earlier in June 2013, The Guardian had reported that the NSA spied on diplomats during the 2009 G-20 London Summit, but no precise program name was revealed at the time.[2]
Diplomatic spying by the United States had been revealed as far back as 2010, when it was revealed that US agencies had spied on the Secretary-General of the United Nations, Ban Ki-moon – at the time, it was not known that this had been done as part of a systematic program.[3]
