“All countries are duty-bound to start serious negotiations on nuclear disarmament,” Khazayee said, addressing the UN General Assembly meeting in New York on Thursday.
He underlined that using and threatening to use “nuclear weapons are in contravention of international law”.
He urged all the countries to fulfill their commitments concerning the nuclear disarmament.
Israel is believed to be the sole possessor of nuclear arms in the Middle-East with over 200 ready-to-launch warheads in its stockpile.
In December 2013, the UN General Assembly unanimously adopted a nuclear disarmament resolution that includes proposals forwarded by Iranian President Hassan Rouhani.
The resolution, adopted on December 5, 2013, calls on nuclear-power states to make more efforts to scale down and ultimately eliminate all types of nuclear arms.
According to the resolution, non-nuclear states should be given guarantees that they will not be threatened or attacked by nuclear weapons.
It also calls on the General Assembly to urge all signatories to the Non-Proliferation Treaty (NPT) to follow up on the implementation of their obligations as agreed in the 1995, 2000 and 2010 Review Conferences.
