The International Atomic Energy Agency (IAEA) has obtained evidence suggesting that documents which have been described as technical studies for a secret Iranian nuclear weapons-related research program may have been fabricated.

The documents in question were acquired by U.S. intelligence in 2004 from a still unknown source -- most of them in the form of electronic files allegedly stolen from a laptop computer belonging to an Iranian researcher. The US has based much of its push for sanctions against Iran on these documents.
