ROUGH CUT (NO REPORTER NARRATION)
STORY: U.S. Secretary of State John Kerry said on Sunday (July 5) that difficult issues still remain in the Iran nuclear talks and that the negotiations could go "either way."
The top U.S. and Iranian diplomats met for a sixth consecutive day on Sunday to try to resolve obstacles to a nuclear accord, including when Iran would get sanctions relief and what advanced research and development it may pursue.
Kerry told reporters during a brief news conference that if there is absolute "intransigence" from Iran, the U.S. has always been willing to walk away from the talks.
But Kerry also added that a deal could be reached "this week" if the sides make the right "choices".
Kerry and Iranian Foreign Minister Mohammad Javad Zarif are trying to meet a Tuesday deadline for a final deal under which Iran would curb its atomic work for more than a decade in exchange for sanctions relief.
