Iran is dismissing a newspaper report that says U.S. intelligence officials have thousands of pages of documents proving Tehran is trying to build a nuclear bomb.

An Iranian Foreign Ministry spokesman, Hamid Reza Asefi, describes the allegations as laughable.

The New York Times reports Sunday the documents were on a stolen Iranian laptop computer obtained from a longtime contact in Iran, and were shown to officials of the International Atomic Energy Agency in July.

The United States accuses Iran of trying to build nuclear weapons, and wants the IAEA to refer Tehran to the U.N. Security Council for possible sanctions. The IAEA board will consider the request during its November 24 meeting.

The Iranian spokesman says the new allegation is an attempt by Washington to affect the board's decision.
