Tehran: Iran`s position in critical nuclear talks is "worrying", with no change on most issues, a Western diplomat said Thursday on the sidelines of negotiations in Vienna.
"It is worrying that there is no evolution on the part of the Iranians on most subjects, including sanctions," the diplomat told AFP on condition of anonymity.
Differences between the two sides on uranium enrichment, the central issue not only in this fifth round of talks but for the past decade, remain "major," the envoy said.
He added: "We have drafted little bits (of an accord) but the complex issues haven`t really been addressed in the drafting process."
The talks between Iran and the five permanent members of the UN Security Council plus Germany aim to strike what would be an historic accord easing fears that the Islamic republic might develop nuclear weapons.
They aim to get a deal by the time an interim accord agreed in November expires on July 20, although the deadline can be pushed back by up to six months if both sides agree to do so.
