U.S. Expands List of Lost Missiles (in Iraq. Over 4000 SAMs missing)

American intelligence agencies have tripled their formal estimate of shoulder-fired surface-to-air missile systems believed to be at large worldwide, since determining that at least 4,000 of the weapons in Iraq's prewar arsenals cannot be accounted for, government officials said Friday.

A new government estimate says a total of 6,000 of the weapons may be outside the control of any government, up from a previous estimate of 2,000, American officials said.

The officials said they did not know whether missiles from Iraq remain there or have been smuggled into other countries, though a senior administration official said Friday that "there is no evidence that they have left the country.''
