"All ambiguities relating to the Iranian nuclear activities were cleared up and the International Atomic Energy Agency's (IAEA) inspectors obtained answers to their questions", the deputy head of the Iranian organization was quoted as saying by the semi-official Mehr news agency.

IAEA chief Mohamed ElBaradei will give a report on Iran's nuclear activities to the next IAEA's board of governors meeting in June, based on the inspectors' findings to be submitted by the end of May.

It is not the first time that Iran has announced that it has answered all questions about its nuclear programme, which the United States in particular suspects is a cover for developing atomic weapons.

At its last session in March, the IAEA alleged that Iran had left certain significant aspects of its activities in the shade, in spite of its commitments made at the end of 2003.

Tehran bridled at the last IAEA resolution and even said that it would not allow the inspectors to continue their work in Iran, but finally yielded.

Saeedi added that during their two week stay which was completed a few days ago, the IAEA's inspectors "discussed with the Iranian experts the two principal subjects of controversy."

These were the manufacture of sophisticated centrifuges to enrich uranium and the "contamination" of equipment with uranium which had a higher level of enrichment than required for civilian purposes.

He added that the inspectors went on a "certain number" of sites and were convinced that Iran had suspended the production and the assembly of the centrifuge parts, under the terms of an agreement on April 9.

The IAEA's experts went to the heavy water factory in Arak, south-west of Tehran, another subject of concern of the international community.

Saeedi said that two or three teams of inspectors were expected in the coming weeks.
