By Louis Charbonneau and Parisa Hafezi GENEVA (Reuters) – Iran and six world powers appeared closer on Friday against clinching an elusive interim deal under which Tehran would curb its contested nuclear program, with diplomats announcing a huge sticking point may have been overcome. A compromise deal over Iran’s insistence that its “proper” to counterpoint uranium be internationally recognized has been proposed, they said, probably opening tips on how to a breakthrough in intensive negotiations that began in Geneva on Wednesday. America and other Western powers say there’s no such factor with no consideration to enrich – a process that can yield each electrical energy and nuclear bombs – however Iran views it as a topic of nationwide sovereignty and an important to any deal that might get to the bottom of a decade-old standoff over its nuclear intentions. Russian Overseas Minister Sergei Lavrov arrived in Geneva on Friday night and deliberate to participate, spokeswoman Maria Zakharova said.
