Nuclear Talks Resume Amid Impasse Worries Envoys from Iran and six world powers have resumed talks over Tehran's nuclear program after issuing dueling proposals during the opening day of the negotiations in the Iraqi capital. The meetings spilled into a second day in apparent efforts to avoid an impasse that could derail the most promising nuclear dialogue with Iran in years. On the table Thursday is an incentive package by the six-nation group - the permanent U.N. Security Council members plus Germany - that seeks to halt the most sensitive part of Iran's nuclear fuel production. Iran put forward a counterproposal after saying it wants the U.S. and Europe to ease sanctions. The West and allies fear Iran's nuclear program could eventually produce atomic weapons. Iran insists its reactors are only for energy and research. BAGHDAD (AP) - Talks between Iran and six world powers snagged Wednesday over dueling proposals concerning Tehran's nuclear program, a tug-of-war that pits international concerns about the Islamic Republic's potential to build atomic weapons against enforcing crippling sanctions on its people. The impasse threatened to dissolve the most hopeful chance of detente in nearly a decade, although both sides agreed to continue negotiations into Thursday. The international community hasn't done something wrong here - we haven't created a suspicious nuclear weapons program that the world doesn't know the answers to. Iran has," a senior U.S. official said early Thursday after the grueling day of discussions that, at times, appeared on the verge of breaking down. They are the party who has acted to create concerns in the international community. However, the official said, the negotiations remain in the beginning of a careful and drawn-out process. "We certainly are not at the end of it," said the U.S. official who spoke on condition of anonymity to discuss the talks more candidly. But they snubbed Iranian calls for an immediate easing of significant economic sanctions imposed on Tehran for flouting U.N. Security Council resolutions that demand the suspension of all enrichment.
