The search for weapons of mass destruction in Iraq has officially come to an end.

"Wrapping up his investigation into Saddam Hussein's purported arsenal, the CIA's top weapons hunter in Iraq said his search for weapons of mass destruction "has been exhausted" without finding any.

Nor did Charles Duelfer, head of the Iraq Survey Group, find any evidence that such weapons were shipped officially from Iraq to Syria to be hidden before the U.S. invasion, but he couldn't rule out some unofficial transfer of limited WMD-related materials."
