The head of the U.N. nuclear agency is calling on Iran to clarify certain aspects of its nuclear program -- as a deadline looms for Tehran to halt uranium enrichment.
Mohamed ElBaradei says there are issues U.N. inspectors must understand before they can be satisfied Iran's nuclear activities are only for peaceful purposes.
ElBaradei spoke to reporters Thursday in Madrid, one day before International Atomic Energy Agency inspectors are expected in Iran. Late last month, the U.N. Security Council called on the I.A.E.A. to report on Iran's nuclear compliance within 30 days.
Also today, the U.S. ambassador to the United Nations said the United States will pursue other options if the Security Council fails to deal with the threat posed by Iran's nuclear program.
John Bolton said those options include cutting the remaining U.S. business links with Iran and convincing American allies to impose travel and financial sanctions on Iran. He added that Iran is a test case for the effectiveness of the United Nations.
But he says the key to solving the problem over Iran's nuclear program lies in the hands of Iranian leaders. The United States accuses Iran of trying to develop nuclear weapons -- a charge Tehran denies.
