UNITED NATIONS/BRUSSELS - The first round of talks between Iran and six world powers on a long-term deal for Tehran to curb parts of its nuclear program in exchange for a gradual lifting of sanctions is expected to take place next month in New York, Western officials said on Monday.

"Waiting for official announcement, which should be soon," a Western official told Reuters about tentative plans to hold the talks as early as mid-February at UN headquarters in New York City. "One of the reasons it's moving to new York is the UN infrastructure, similar to Geneva."

Another Western confirmed the official's remarks.
