France says negotiations are still possible with Iran over its controversial nuclear program if Tehran suspends its nuclear fuel activities. French Foreign Minister Philippe Douste-Blazy made the remarks on Friday in Geneva. He said France would wait for International Atomic Energy Agency Chief Mohamed ElBaradei's report early next month on Iran's activities before deciding the next course of action. On Thursday, the IAEA expressed "serious concern" over Iran's decision this week to resume uranium conversion -- a step before uranium enrichment -- which can be used to generate electricity or to fuel a nuclear weapon. Europe and the United States have warned they will refer Iran to the U.N. Security Council for possible sanctions if it does not cooperate. The United States suspects Iran of pursuing a covert atomic weapons program, a charge Tehran denies.
