DUBAI (Reuters) -Iran's Supreme Leader Ayatollah Ali Khamenei said U.S. demands that Tehran stop enriching uranium are "excessive and outrageous", state media reported, voicing doubts whether talks on a new nuclear deal will succeed.
"I don't think nuclear talks with the U.S. will bring results. I don't know what will happen," Khamenei said, adding that Washington should avoid making "nonsense" demands in the negotiations, four rounds of which have been held.
