The Israeli government is seeking an explanation from the U.S. after becoming the latest country to be caught up in NSA spying. Documents leaked by Edward Snowden show the NSA monitored the emails of then-Prime Minister Ehud Olmert and other top Israeli officials in 2009. On Monday, Israeli Prime Minister Benjamin Netanyahu called the surveillance unacceptable.

Israeli Prime Minister Benjamin Netanyahu: “Concerning matters published in the past few days, I have asked for an examination in the matter. In the close ties between Israel and the United States, there are things that must not be done and that are not acceptable to us.”
