Kerry says gaps remain in talks about Iran's nukes
US Secretary of State John Kerry warned of "serious gaps" in talks about a nuclear deal with Iran, but as Monday's deadline approached his German counterpart said Tehran and six world powers have "never been closer" to agreement since they started negotiating more than six years ago.
German Foreign Minister Frank-Walter Steinmeier also said Saturday that both sides are "still far apart" on certain questions. But he suggested the differences are bridgeable, declaring that the talks have reached "a moment of truth." Still, he said, success or failure "is still completely open at this point."
Steinmeier spoke after arriving in Vienna to join Kerry's efforts to move the talks forward and shortly before meeting with the chief US diplomat.
