IAEA team arrives in Iran seeking details

Tehran: A team from the UN nuclear watchdog led by its second-in-command arrived in Tehran on Wednesday seeking details about Iran's offer to answer unresolved questions about its disputed nuclear programme.

Iran has offered to draw up an "action plan" to address suspicions its nuclear programme has military goals. Tehran insists its aims are purely civilian but faces the prospect of
more UN sanctions for failing to convince world powers.

Olli Heinonen, deputy director of the UN International Atomic Energy Agency (IAEA), is heading the delegation which is expected to hold talks with Iran's chief nuclear negotiator Ali Larijani and his deputy Javad Vaeedi.

"A technical, legal and political delegation of the International Atomic Energy Agency, headed by Olli Heinonen, ... arrived in Tehran on Wednesday morning," the official IRNA news agency reported.

The United States and its European Union allies wonder whether Iran's offer of transparency is anything more than an exercise to buy time and avert further UN measures.

The IAEA wants explanations for traces of highly enriched - bomb-grade - uranium found on some equipment.

It also wants to know more about experiments with plutonium, the status of research into an advanced centrifuge able to enrich uranium three times as fast as the model Iran now uses, and documents showing how to cast uranium metal for a bomb core.
