ROUGH CUT (NO REPORTER NARRATION)

Iran and six world powers have not reached any deal yet that would end Tehran's decade-long standoff with the West over its nuclear program, U.S. Secretary of State John Kerry said on Friday.

"I want to emphasize there are still some very important issues on the table that are unresolved. It is important for those to be properly, thoroughly addressed. I want to emphasize there is not an agreement at this point in time," Kerry told reporters shortly after arriving in Geneva.

Kerry plans to meet with Iran Foreign Minister Javad Zarif to narrow differences.
