U.S. calls meeting on Iran sanctions

VIENNA (Reuters) - The United States said on Wednesday it would host a meeting of world powers on September 21 to discuss broadening U.N. sanctions against Iran for its refusal to suspend nuclear activity.

The meeting of the five permanent U.N. Security Council members and Germany is due to focus "largely on a discussion of what sanctions will be included" in a new Council resolution, U.S. State Department spokesman Sean McCormack said.

The announcement in Washington came during a meeting of the International Atomic Energy Agency (IAEA) in Vienna, where western countries questioned a deal between Tehran and the IAEA, meant to bring transparency to Iran's nuclear program.

The August 21 deal commits Iran to answer five-year-old IAEA questions about its nuclear program over a timeline of a few months, while effectively allowing Tehran to continue to enrich uranium -- a process that can be used to produce nuclear bombs.

Iran says it is entitled to run a nuclear program it bills as designed solely to generate electricity. Chief nuclear negotiator Ali Larijani, speaking in Tehran, reiterated on Wednesday that Iran would not suspend uranium enrichment.

The United States, which suspects Iran of seeking nuclear bombs, believes mild U.N. sanctions need to be tightened to force Iran to suspend uranium enrichment. It fears the deal with the IAEA might delay its bid for stronger sanctions.

During the meeting of IAEA governors in Vienna, it appealed for support from the 35-nation body for fresh sanctions on Iran.

But referring to such pressure, Iran warned that any "political interference" could kill the deal. "Let the IAEA do its job," Iranian Ambassador Ali Asghar Soltanieh said.
