Israeli Prime Minister Benjamin Netanyahu, commenting on allegations the US had spied on Israel's leaders, said on Monday such activity was unacceptable and had no place in the allies' close relationship.
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 defence officials.
"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.
He did not elaborate on whether Israel intended to ask Washington for clarifications.
