ISTANBUL — Iran said differences were narrowing Friday at talks with six world powers who hope Tehran will curb its ability to turn nuclear power into atomic arms, but other nations said progress remained elusive.
"Compared to the Geneva talks, the negotiations in Istanbul are being held in a more positive way," Iranian delegate Abolfazl Zohrevand said, referring to talks in the Swiss city that ended last month with only an agreement to meet again in Turkey. "There are good signs that the two sides will make progress.""They didn't get what they had hoped to get from pressure and sanctions," he said. "They are showing some flexibility. This is helping both sides to be optimistic."
