TEHRAN, April 4 (Xinhuanet) -- Iran reiterated on Sunday that it was not hiding any of its nuclear facilities from UN inspectors andits resumption of work on a key part of the nuclear fuel cycle was not a violation of its commitment to suspend uranium enrichment activities.

    "There is no nuclear site that the International Atomic Energy Agency (IAEA) is not aware of and that we have hidden from IAEA inspectors," Foreign Ministry spokesman Hamid-Reza Asefi told a press briefing.

    "We have a transparent and constructive cooperation with IAEA, and this will continue. We are committed to our engagements, and upto now have not violated any of them," Asefi said.

    Meanwhile, Asefi denied a western news agency report claiming that traces of enriched uranium have been found in one of Iran's nuclear sites, terming such report as "baseless and false."

    "The IAEA experts have not reported any case to this effect at the end of their recent visit to Tehran," Asefi stressed. He also described IAEA Director General Mohammed ElBaradei's upcoming one-day visit to Iran on Tuesday as "important".

    In a deal with the IAEA late last year, Tehran agreed to suspenduranium enrichment and related activities while UN inspectors delved into its program.

    But Asefi claimed the resumption of work at a uranium conversionfacility near the central city of Isfahan which was announced last week was not a violation of the deal.

    "The resumption of activities at Isfahan does not violate any ofour commitments. It is for the production of UF4 in an experimentalfashion, which has nothing to do with our commitment to voluntarilysuspend uranium enrichment," Asefi said.

    Asefi also confirmed that a new visit by IAEA inspectors would take place later this month, with the latest probe focusing on "thesuspension of enrichment and the G-2 centrifuge. Enditem
