"With regard to things published in the past few days, I have asked for an examination of the matter," Netanyahu said in broadcast remarks, in a clear reference to the alleged espionage.

According to undisclosed Israeli officials, Netanyahu's demand for the release of the Israeli spy through the platform of peace talks with the Palestinians could be executed in one of two ways: A release of the Israeli spy as part of an Israeli-Palestinian agreement pushed by the Americans for next month, or through a deal aimed at releasing Arab-Israeli prisoners.

Documents leaked on Friday by former US National Security Agency contractor Edward Snowden showed the NSA and its British counterpart GCHQ had in 2009 targeted an email address listed as belonging to then-Israeli Prime Minister Ehud Olmert and monitored emails of senior defense officials.
"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," Netanyahu said, speaking during a Likud party faction meeting.
On Sunday, several Israeli cabinet members and lawmakers said disclosure of US spying on Israel was an opportunity to press Washington to free jailed Israeli agent Jonathan Pollard. Netanyahu informed Likud party members on Monday that he had met with Pollard's wife Ester "and updated her on our unceasing efforts to free Jonathan."
Pollard was sentenced to a life term in 1987 in the United States for spying for Israel. A succession of US presidents have spurned Israeli calls for his pardon.
