German intelligence services eavesdropped on calls made by U.S. Secretary of State John Kerry and predecessor Hillary Clinton, according to German magazine Der Spiegel.

The Guardian reports:

The German foreign intelligence agency, BND, tapped a satellite phone conversation Kerry made in 2013 and also recorded a conversation between Clinton and former UN secretary-general Kofi Annan a year earlier, according to the magazine.

The three officials were not directly targeted with phone calls collected by accident within the context of other operations, according to the report. In Clinton’s case, the call reportedly took place on the same “frequency” as a terror suspect.

The tapping of Clinton’s call was reported on Friday by German public broadcaster ARD and Munich daily Sueddeutsche Zeitung.
