Iran has rejected a plan to send its uranium to be processed overseas hours after President Mahmoud Ahmadinejad said his country was ready to cooperate with the West, sources told the New York Times on Thursday night. The report quoted European diplomats and American officials as saying that Teheran had informed the UN of its decision after it refused to oblige to the part of the draft agreement formulated during a conference in Vienna last week calling for the state's stockpile of uranium to be transferred to Russia.
