Talks between Iran and six world powers are going into a second day with no sign of progress on U.N. Security Council demands that Tehran curb its nuclear activities.
An official at the negotiations said the first meeting on Monday gave little reason to presume that Iran would relent and address the demands. That would dash hopes of a renewed meeting in the new year.
Delegates from Iran, the U.S., Russia, China, Britain, France and Germany are meeting on Tuesday at a conference centre in Geneva.
Tehran insists its nuclear programme is only designed to provide more power for its growing population. Yet as Iran builds up its capacity, neither Israel nor the U.S. are ruling out military action if Tehran fails to heed U.N. Security Council demands.
