A senior Iranian negotiator said on Saturday Tehran was seeking the explicit recognition of a "right" to enrichment in any deal with world powers in Geneva, Iranian media reported.

(AFP/file/Behrouz Mehri) "We are insisting on our right to enrichment, which should be clearly recognised in the draft agreement," deputy foreign minister Abbas Araqchi was quoted as telling Iranian reporters late Saturday, the fourth day of intensive talks. Araqchi said the negotiations were "making progress but slowly." He added the negotiations were now in the 11th hour and that "most of the differences of opinion have been resolved." He did not further elaborate though. "There has been progress of 98 percent in the negotiations, but maybe the remaining two percent are way more important than all the other issues," Araqchi said, the ISNA news agency reported. The remarks came late on Saturday, after foreign ministers from the so-called P5+1 group of the United States, Britain, France, China and Russia plus Germany converged to the Swiss city to help narrow the differences. The talks, the third such gathering in five weeks, are aimed at an elusive deal that would curb or freeze Iran's nuclear activities in exchange for limited relief from sanctions that are hurting its economy. Iran insists its nuclear programme is peaceful, but has failed to allay the international community's suspicions it is aimed at acquiring atomic weapons. - AFP/fa
