TEHRAN, Feb 4: Iran on Sunday vowed to defy a UN resolution calling for a freeze to its controversial nuclear work but promised to open up its disputed uranium enrichment facility in Natanz to the media.

“We believe this resolution has legal and executive problems, we will not implement it, as we have said before,” the head of Iran's Atomic Energy Organization Gholamreza Aghazadeh said, quoted by semi-official Mehr news agency.

He was referring to UN resolution 1737 that calls on the Islamic republic to halt uranium enrichment -- the process that makes nuclear fuel as well as the fissile core of an atomic bomb.

The resolution imposes limited sanctions on Iran for its refusal to freeze such work, which the West fears could be diverted to make weapons. Iran insists its nuclear programme is entirely peaceful.

Aghazadeh also promised journalists a visit to Iran's enrichment facility in Natanz “in seven or eight days to see the latest stages of the work,” and that “good nuclear news will be announced soon,” the Fars news agency reported. He did not give further details on the nature of the news, which has been promised by a number of Iranian officials over the past weeks.—AFP
