U.S. President Barack Obama's spokesman Jay Carney evaded answering a question on whether the National Security Agency listened to Prime Minister Benjamin Netanyahu's calls.
According to the Washington Examiner, Carney refused to speak of "specific assurances" regarding Netanyahu.
"I just don't have anything more specific about specific alleged [NSA operations]," the Washington Examiner quoted Carney as saying.
On Sunday, Obama reportedly apologized to German Chancellor Angela Merkel after it was discovered that the NSA was tapping her phone.
According to the Wall Street Journal, the National Security Agency has terminated several programs used to spy on world leaders after the Obama administration became aware of the eavesdropping.
An internal review conducted by the Obama administration revealed that the NSA was monitoring "some 35 world leaders," which has drawn international outrage in recent days following the news that the NSA was tapping Merkel's phone and calls in France.
