Meanwhile on Monday — President Bush warned Iran again that it will face tough sanctions if it rejects a new offer from the U.S. and European nations to rejoin nuclear talks.

• President Bush: “If Iran’s leaders reject our offer, it will result in action before the Security Council, further isolation from the world and progressively stronger political and economic sanctions. I have a message for the Iranian regime. America and her partners are united. We have presented a reasonable offer. Iran’s leaders should see our proposal for what it is —-— an historic opportunity to set their country on a better course.”
