Us-iran Relations, Nuclear Disarmament | featured news

Iran followed the United States on Sunday in denying that the two countries had scheduled direct bilateral negotiations on Iran's controversial nuclear program. The New York Times, quoting unnamed U.S. administration officials, had said on Saturday that secret exchanges between U.S. and Iranian officials had yielded agreement "in principle" to hold one-on-one talks.

Iran warned the United States Tuesday not to return a U.S. aircraft carrier "to the Persian Gulf region." U.S. officials rejected the "warning" and another recent threat from Tehran that it could close the Strait of Hormuz. The White House and U.S. State Department called the latest threats signs that sanctions against Iran, the result of a standoff over its nuclear activities, are working.

Global nuclear conference that opens today is shaping up as a showdown between Iran and U.S.
