Germany's foreign intelligence agency eavesdropped on calls made by Secretary of State John Kerry and his predecessor Hillary Clinton, Der Spiegel reported Saturday.
The agency recorded a satellite phone conversation Kerry made in 2013 as part of its surveillance of telecommunications in the Middle East, the weekly paper reported.
The paper said the calls were collected accidentally, and that the U.S. officials were not deliberately targeted, and that the recordings were destroyed immediately.
In Clinton's case, the call reportedly took place on the same "frequency" as a terror suspect, Der Spiegel said.
If the revelations are true, they would be embarrassing for a German government angry over alleged U.S. spy activity in the European country.
Documents leaked by former National Security Agency contractor Edward Snowden last year showed that German Chancellor Angela Merkel was one of the agency's targets.
