More on Iran's nuclear program...

Lots of questions....very few answers...this is from the Washington Post.

Iranian nuclear engineer Mohsen Fakhrizadeh lectures weekly on physics at Tehran's Imam Hossein University. Yet for more than a decade, according to documents attracting interest among Western governments, he also ran secret programs aimed at acquiring sensitive nuclear technology for his government.

Experts at the International Atomic Energy Agency (IAEA) have repeatedly invited Fakhrizadeh to tea and a chat about Iran's nuclear work. But for two years, the government in Tehran has barred any contact with the scientist, who U.S. officials say recently moved to a new lab in a heavily guarded compound also off-limits to U.N. inspectors.

The exact nature of his research -- past and present -- remains a mystery, as does the work of other key Iranian scientists whose names appear in documents detailing what U.N. officials say is a years-long, clandestine effort to expand the country's nuclear capability. The documents, which were provided to the IAEA, the U.N. nuclear agency, in recent months by two countries other than the United States, partly match information in a stolen Iranian laptop turned over by Washington.

IAEA officials say these documents identify Fakhrizadeh and other civilian scientists as central figures in a secret nuclear research program that operated as recently as 2003. So far, however, Iran is refusing to shed light on their work or allow U.N. officials to question them. After being presented with copies of some of the new documents, Tehran denied that some of the scientists exist.
