From The New York Times:

The report, buttressed by evidence not previously disclosed, concluded that Iran had been secretly engaged in behaviors that suggested that it was seeking to construct a nuclear weapon. The report also asserted that Iran might be researching ways to deliver a nuclear weapon by means of a missile warhead. It was the first time that the agency, an arm of the United Nations, had made such assertions.

President Mahmoud Ahmadinejad of Iran led the verbal assault on the report, saying it had been orchestrated by Iran’s enemies, principally the United States, which he said had dictated the report’s findings.
