VIENNA (Reuters) - Iran told six big powers on Friday it would not accept their "excessive demands" after the latest talks on lifting sanctions against Tehran in exchange for curbs on its nuclear work yielded no breakthrough, with a deadline for a deal just a month away.
U.S. Under Secretary of State for Political Affairs Wendy Sherman said it was Iran that would need to shift its position: "What is still unclear is if Iran is really ready and willing to take all the necessary steps to assure the world that its nuclear programme is and will remain exclusively peaceful."
