VIENNA (Reuters) - Iran and world powers locked horns on Wednesday over the future of a planned Iranian nuclear reactor that could yield plutonium for bombs as the United States warned "hard work" will be needed to overcome differences when the sides reconvene in April.
The meeting in Vienna was the second in a series that the six nations - the United States, China, Russia, Germany, France, Britain - hope will produce a verifiable settlement on the scope of Iran's nuclear programme, ensuring it is oriented to peaceful ends only, and put to rest the risk of a new Middle East war.
