"The nuclear weapon states have not made progress in eliminating their nuclear weapons. The role of nuclear weapons in security policies of the nuclear weapons-states has not diminished," Iran's Minister of Foreign Affairs Javad Zarif said at the 2015 NPT Review Conference here yesterday.
"Some nuclear weapons-states are modernising their nuclear arsenals and planning research on new nuclear warheads, others have announced their intention to develop new delivery vehicles for nuclear weapons," he said.
"The transfer of nuclear technology continues to face impediments inconsistent with the Treaty, and no progress has been made to achieve universal adherence to the Treaty in the Middle East," he said.
Iran demanded that the nuclear-weapons countries immediately cease their plans to further invest in modernising and extending the life span of their nuclear weapons and related facilities.

"We firmly believe that any use or threat of use of nuclear weapons would be a crime against humanity and a violation of the principles of the Charter of the United Nations and international law, in particular international humanitarian law," he said.
"The nuclear-weapon states shall seriously refrain, under any circumstances, from the use or threat of use of nuclear weapons against any non-nuclear-weapon states parties to the Treaty," Zarif said, adding that reductions in deployments and in operational status cannot substitute for irreversible cuts and the total elimination of nuclear weapons.
The 2015 Review Conference will run at UN Headquarters through till May 22.
The President-designate of the Conference is Ambassador Taous Feroukhi from Algeria.
The NPT is a landmark international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy and to further the goal of achieving nuclear disarmament and general and complete disarmament.
