WikiLeaks has published a list it claims shows the U.S. National Security Agency eavesdropped on senior German officials other than Chancellor Angela Merkel.

Reports two years ago that Merkel's phone had been targeted by the NSA prompted diplomatic friction between Berlin and Washington. German prosecutors recently dropped their probe into the case citing lack of concrete evidence.

WikiLeaks published a redacted list Wednesday of 69 phone numbers it said belonged to senior officials at Germany's economy and finance ministries, among others. There was no immediate confirmation of the accuracy of the list.

German newspaper Sueddeutsche Zeitung, which said it had been given access to the document, reported on its website that the list appeared to be from a period between 2010 and 2012.
