Israeli Prime Minister Benjamin Netanyahu says his country will not draw any "red lines" for action regarding Iran's disputed nuclear program.
In comments following a meeting with Canadian Prime Minister Stephen Harper in Ottawa, Netanyahu said Israel had the right to defend itself and reserved its "freedom to maneuver in the light of threats."
He added that he did not believe negotiations will resolve the conflict, saying Tehran used talks to "deceive and delay."
U.S. President Barack Obama, in comments to a U.S. magazine, said he did not "bluff" as president and repeated that Washington considers a nuclear-armed Iran "unacceptable."
He made the remarks ahead of a visit to Washington on March 5 by Netanyahu.
The West suspects Iran's nuclear program will be used to manufacture nuclear weapons.
Tehran denies that.
