IRAN WARNED SUNDAY THAT IT WOULD RESPOND TO ANY HARSH ACTION BY THE U.N. SECURITY COUNCIL WITH AN EQUALLY TOUGH _ BUT UNSPECIFIED _ RESPONSE AND INSISTED AGAIN IT WOULD CONTINUE URANIUM ENRICHMENT. ON SATURDAY, IRAN OFFERED TO ALLOW THE RESUMPTION OF INTRUSIVE "SNAP" INSPECTIONS OF ITS NUCLEAR FACILITIES IF THE U.N.'S INTERNATIONAL ATOMIC ENERGY AGENCY WERE TO RESUME ITS LEAD ROLE MANAGING IRAN'S DISPUTE WITH THE INTERNATIONAL COMMUNITY. THE WHITE HOUSE REJECTED THE PROPOSAL. "OUR REACTIONS ARE TOTALLY COMPATIBLE WITH THE ACTIONS OF THE OTHER PARTIES. AGAINST RADICAL ACTIONS, IRAN WILL REACT ACCORDINGLY. IF THE U.N. SECURITY COUNCIL MAKES DECISIONS, THE ISLAMIC REPUBLIC OF IRAN WILL DEFINE AND ARRANGE ITS COOPERATION WITH THE AGENCY COMPATIBLE WITH THAT," FOREIGN MINISTRY SPOKESMAN HAMID REZA ASEFI WAS QUOTED AS SAYING BY THE ASSOCIATED PRESS.
