VIENNA (Reuters) - Iran would only consider halting nuclear enrichment to a purity of 20 percent if it first received fuel for a medical reactor from major powers, a senior official said on Friday.

""We will not, even for a second, suspend our nuclear enrichment activities,"" Ali Asghar Soltanieh, Iran's envoy to the UN nuclear watchdog told Reuters.
Asked if this also included 20 percent enrichment that Iran launched four months ago, he said: ""Yes, of course.""
The United Nations Security Council adopted a fourth round of sanctions on Wednesday to punish Iran for its refusal to stop enriching uranium.
Iran escalated its enrichment work after the West failed to agree to Iran’s terms for a swap deal. Iran wanted a simultaneous exchange of nuclear fuel.
However, Iran signed a deal with Turkey and Brazil last month agreeing to deposit its low-enriched fuel in Turkey until it receives the 20 percent nuclear fuel to power its medical reactor in Tehran.
