Vienna: Iran wants more talks on a UN-drafted nuclear proposal, including guarantees that it will receive the reactor fuel, Tehran's envoy to the International Atomic Energy Agency said on Monday.

Tehran has said it wants changes to the draft deal, in which it would send its low-enriched uranium (LEU) abroad for further processing to turn it into more refined fuel for a research reactor.

Iranian envoy Ali Asghar Soltanieh said more talks were needed "in order to ensure that our technical concerns, especially the issue of guarantees of fuel supply, are taken into consideration".
