Iran says 'serious disagreements' may collapse US talks

Iran's Foreign Minister Abbas Araghchi said on Saturday both Tehran and Washington showed their determination to make progress in the talks held in Muscat.
However, he said, "sometimes determination alone is not enough, and the disagreements may be so serious that reaching a result becomes impossible."
"Some of the disagreements are serious, and some have their own complexities, but we are hopeful that we can move forward quickly, and the progress so far has been good. I am satisfied with the process and pace of the negotiations," he added.
Araghchi said the two sides were engaged in a "much more serious" round of talks today.
"There are still disagreements, but it was evident that both sides are serious," he said. Araghchi said, "We are very cautiously optimistic."
The Iranian top diplomat ruled out talks on any non-nuclear issues. "We only discuss the nuclear issue and won't accept negotiations on any other topic."
Reuters had earlier quoted an Iranian official as saying that the Iran-US talks are not limited to Tehran’s disputed nuclear program but also include its missile program.
The source said the missile program has become the sticky point in Iran-US talks.
