Iran pledged Sunday it was still committed to suspending parts of its sensitive nuclear activities as of Monday and that alarm over its last minute uranium conversion activities was merely US "propaganda". "The suspension will begin tomorrow. We have said that we will suspend our enrichment activities and we will do it," foreign ministry spokesman Hamid Reza Asefi told reporters.
Iran agreed a week ago in a deal with Britain, France and Germany to suspend as of Monday all its uranium enrichment related activities, including making uranium gas, as a confidence-building measure in order to avoid being taken to the UN Security Council.
But diplomats have said that Iran was continuing to produce the uranium feedstuff that is the first step in the enrichment process, only days before the deadline - in what critics of the regime have taken as an act of bad faith.
In addition, US President George W. Bush sharply warned Iran on Saturday that reports the Islamic republic has accelerated production of the feedstuff known as UF6 was a "very serious matter".
But Asefi said "the news about the production of UF6 ahead of the suspension is just a part of the propaganda to weaken relations between Iran and the (International Atomic Energy) Agency, and the work on building trust with the Europeans."
"What we have been doing over the past few days conforms with the Paris accord and has been carried out under the supervision of the agency," he asserted.
This week the IAEA will be checking Iran's enrichment suspension, ahead of a meeting of the IAEA's 35-nation board of governors in Vienna on Thursday. The suspension must be verified if Iran is to escape a possible referrel to the Security Council.
Iran claims its nuclear programme, parts of which it long failed to disclose, is a strictly peaceful effort to produce electricity. The United States says it is merely a convenient cover for weapons development.
In the latest US allegations, US Secretary of State Colin Powell told reporters en route to a meeting of Asia-Pacific leaders in Chile that Washington has information suggesting that Iran is seeking to adapt its missiles to carry nuclear warheads.
