US Secretary of State John Kerry (R)

US Secretary of State John Kerry said Saturday that world powers were "united" in their nuclear talks with Iran, amid speculation of splits with France, and stressed that he would not "rush" into a bad deal.
"I emphasise: We are united in our goal, our approach, our resolve and our determination to ensure that Iran's programme is entirely peaceful," Kerry said in Switzerland before leaving for London for talks with his German, French and British counterparts.
