The U.S. government isn't immune to phone hacking. German news magazine Der Spiegel is reporting that Israeli intelligence spied on Secretary of State John Kerry's phone calls during peace negotiations last year.
The report will probably put some strain on America's relationship with Israel. But, the U.S. is still a big supporter of the country. It recently sent $225 million in support for the Iron Dome missile defense system.
Kerry was a mediator last year between Israel, Palestinians and some Arab states. The Israelis and at least one other intelligence service listened in on some of Kerry's phone calls to Middle Eastern negotiating partners.
At the time, some of these calls were not made on encrypted equipment, but instead on normal telephones, with the conversations transmitted by satellite. Intelligence agencies intercepted some of those calls. The government in Jerusalem then used the information obtained in international negotiations aiming to reach a diplomatic solution in the Middle East.
Kerry has a tense relationship with Israel. He visited Israel again recently to help mediate the current conflict, but it didn't go so well and an agreement couldn't be reached.
