Israeli intelligence reportedly listened in on U.S. Secretary of State John Kerry's telephone calls during Middle East peace negotiations last year. Der Spiegel quotes "a reliable source" saying Israel eavesdropped on conversations made on telephones that were not encrypted. It reports that at least one other foreign intelligence service listened on Kerry's talks, as well, but did not specify which. Neither the U.S. nor Israel has commented. At the same time, documents newly released by Edward Snowden show that the NSA works closely with its Israeli counterpart SIGINT National Unit and provides surveillance assistance to monitor and target Palestinians, as do British and Jordanian agencies.
