Ali Akbar Javanfekr, an adviser to Iranian President Mahmoud Ahmadinejad, said that that US Secretary of State Hillary Clinton's statement that key nations had reached agreement on strong UN sanctions will not hurt Iran but instead will alienate the United States.

Speaking before the Senate Foreign Relations Committee, Ms Clinton said on Tuesday that the United States has been "working closely" with its international partners - the group known as the P5 plus 1 - on a resolution to present to the UN Security Council.

The P5 plus 1 includes the five permanent member of the Security Council - the United States, China, Russia, France and Britain - as well as Germany.

That draft resolution restates the Security Council's demand that Tehran suspend enrichment activities and other proliferation-sensitive nuclear activities. It requires Tehran to cooperate fully with the U.N. nuclear watchdog International Atomic Energy Agency.
