MOMENTUM BUILDS

An Iraqi scientist associated with Saddam Hussein's nuclear program has surrendered to U.S. authorities in Baghdad, U.S. defense officials said Friday.

The officials identified the scientist as Abdullah Abbus Khandush, and said he was cooperating with the United States but that any information he was providing would not be made public, at least in the short term.

It's hoped the scientist, who was captured Thursday, will be able to provide information about Iraq's nuclear weapons program. Disarming the regime of suspected nuclear, chemical and biological weapons was a prime reason given by the Bush administration for launching the war that toppled Saddam. To date, no such weapons have been found.
