UNDER SECRETARY BURNS: We are very satisfied by the results of today's meetings here in Vienna. We consider them a step forward in our quest to deny Iran a nuclear weapons capability and I think there's no question at the four meetings that Secretary Rice has had at ministerial level with this group, this was by far the most substantive and the most concrete.

I will say this: Because of the nature of the diplomacy and because of the delicate aspect of the negotiations that will now ensue with Iran, I am not going to be giving you the details of the package that was agreed to tonight. I'm not going to give you details of the positive side or the negative side. That was the agreement of everybody in the room, and so the United States will stick to that agreement.
