Iran's top diplomat Mohammad Javad Zarif says Tehran has ** interest in building an atomic bomb, despite Western powers' claims otherwise. Zarif's comments, in a television interview due to be broadcast Sunday, when Iran engages in talks with the five permanent members of the United Nations Security Council plus Germany aimed at a grand bargain reducing in scope the Islamic republic's nuclear activities in return for sanctions relief. "I will commit to everything and anything that would provide credible assurances for the international community that Iran is **t seeking nuclear *******, because we are **t," Zarif told NBC's "Meet the Press" from Vienna, where the talks are taking place. "We don't see any benefit in Iran developing a nuclear ******." Zarif rejected "calculations" suggesting the Shiite country would seek to develop nuclear ******* to guard itself against its Shiite neighbors.
