Germany’s foreign intelligence agency eavesdropped on US Secretary of State John Kerry and his predecessor Hillary Clinton, German media reports say.
Der Spiegel magazine says the calls were collected accidentally and the recordings were destroyed immediately.
Mr Kerry has reportedly spoken to his German counterpart, Frank-Walter Steinmeier, about the claims.
Correspondents say the reports will embarrass Germany after a row about the US spying on Chancellor Angela Merkel.
Der Spiegel said the German intelligence agency had tapped a satellite phone call Mr Kerry made in 2013.
Reports in German daily newspaper Suddeutsche Zeitung and public broadcasters NDR and WDR said documents passed to the CIA show German spies had also eavesdropped on Hillary Clinton when she was US Secretary of State, BBC informs.
