If Iranian negotiators do not show flexibility in nuclear talks, reaching a deal with major powers in the coming days will be "quite difficult", a Western diplomat said on Friday.
"We are negotiating in an extremely intense way, there is a collective and multilateral effort to get there. But if the Iranians do not move, it seems quite difficult and for now they are not moving a lot," the Western diplomat said on condition of anonymity.
Any initial easing of UN sanctions for Iran if a deal is clinched, one of Tehran's main demands, could include "gestures" such as removing individuals and entities from an asset freeze and travel ban blacklist, he said.
Key sticking points were enrichment and research and development, and the lifting of UN sanctions. "Nobody can reasonably think that UN Security Council sanctions could be lifted like that. But we can make certain gestures concerning certain individuals and certain entities but we can't go much further," he said.
