The International Atomic Energy Agency's 35-nation board is expected to vote Saturday on a motion that could eventually see Iran referred to the United Nations Security Council for its controversial nuclear activities.
The European Union proposed the motion Friday. It puts off immediate referral to the Security Council, but leaves that option open. It also condemns Iran for past violations of nuclear safeguards.
EU negotiators softened the draft resolution in an apparent effort to gain support from Russia and China, which both oppose referral to the Security Council.
Diplomats say Iran is threatening to resume sensitive uranium enrichment and to limit inspections if the IAEA adopts the resolution. Tehran denies western accusations that it is secretly pursuing nuclear weapons.
