Obama committed to denying Iran nuclear weapon: US

Washington: US President Barack Obama is firmly committed to denying Iran a nuclear weapon, Washington`s ambassador to the United Nations Samantha Power said Monday.

"He will keep his commitment whether the negotiations collapse or produce a diplomatic solution that meets our bottom line," Power told the pro-Israel lobby AIPAC ahead of a speech by visiting Israeli Prime Minister Benjamin Netanyahu.

"If diplomacy should fail, we know the stakes of a nuclear-armed Iran as well as everyone here, we will not let it happen," she added.
